Best Fish Tanks of 2026: Top Picks for Every Aquarist

The Jengu M1 is a 5.3-gallon smart desktop aquarium designed for fish keepers who want modern technology and clean aesthetics without the complexity of a traditional setup. It suits beginners setting up their first betta tank as well as experienced hobbyists who appreciate app-driven convenience for busy schedules or frequent travel.

The standout feature is the free Jengu app, which gives you full remote control over feeding schedules, seven distinct lighting modes, pump flow rates, and real-time temperature monitoring complete with historical data and alerts. The integrated auto feeder means you can go away for a weekend without worrying, and the child and pet lock is a genuinely practical touch for households with curious kids or cats.

Build quality impresses for this category. The tank uses 5mm low-iron glass that renders colors more accurately than standard float glass, and the rimless, frameless design looks premium on a desk or countertop. All hardware is concealed in a hidden rear chamber, so the viewing experience is clean and unobstructed. The hinged lid is sturdy, rated to hold up to 15 pounds, and props itself open hands-free during maintenance.

There are a few considerations worth noting. The price is higher than entry-level kits, and the smart features depend on a stable 2.4GHz WiFi network. A heater is not bundled in the box, which is a notable omission for anyone keeping tropical species in a cooler environment. Filter media are also classified as consumables and fall outside the one-year warranty coverage.

Overall, the Jengu M1 earns its place as one of the more thoughtfully engineered small aquariums available today. The combination of app control, dual filtration, quiet operation, and a tool-free water change system addresses the most common pain points of fish keeping in a compact, stylish package. If you want a desktop aquarium that works as hard as it looks good, the M1 is a compelling choice.

Tank Volume: 5.3 gallons total capacity, recommended fill 3.8 to 4.6 gallons. Glass Dimensions: 17.3 inches long x 9.4 inches wide x 9.1 inches tall. Overall Dimensions with Lid: 17.6 inches long x 9.8 inches wide x 11.6 inches tall. Item Weight: 16.1 pounds.

Material: 5mm low-iron glass tank body with ABS housing on the lid and filtration components. Color: White. Shape: Square, rimless design. Pump Noise Level: Approximately 28 dB. Pump Flow Settings: Three levels, low, medium, and minimum.

Lighting: Full-spectrum LED integrated into the lid with seven preset modes including Amazon, Stream, White, Nightlight, Daylight, Color Flow, and Plant Grow, plus custom RGB. Connectivity: 2.4GHz WiFi, free Jengu app for iOS and Android, no subscription required.

Filtration: Dual media cartridge with mechanical sponge lasting up to 90 days and bio media lasting up to 180 days. Auto Feeder: Integrated into lid, schedule-controlled via app. Warranty: One year covering tank, pump, smart lid, and LED. Filter media not covered as consumables. Model Number: M1-White. ASIN: B0GVQQ5NYH.

If you are considering the Jengu M1, start by thinking about what species you plan to keep. The three pump flow settings make this tank genuinely versatile: low flow for a single betta, medium for a small guppy school, and the minimum setting for a delicate shrimp colony. Just remember that tropical fish typically need water temperatures between 76 and 82 degrees Fahrenheit, so you will want to budget for a compatible slim heater since one is not included.

The smart features are most valuable for people who travel regularly or have unpredictable schedules. The remote feeding and scheduling via the Jengu app remove the biggest stress of fish ownership. Before purchasing, confirm your home router broadcasts a 2.4GHz WiFi network, as the tank will not connect to 5GHz-only networks. Most modern dual-band routers support both, but it is worth checking.

On maintenance, the dual filtration cartridge is a genuine time saver. The one-piece lift-out design and the drain-tube water change system mean routine care takes minutes rather than the better part of an afternoon. Factor in the cost of replacement filter cartridges when budgeting, as these are consumable items not covered by the warranty. The app sends reminders when media is due for a swap, which helps you stay on schedule without guesswork.

For desk or countertop placement, measure your available space carefully. The tank footprint is approximately 17.6 inches long by 9.8 inches wide with the lid on, and you will want a few extra inches of clearance behind for the rear chamber access and above for the lid to open fully. The white finish and rimless glass suit modern, minimalist interiors particularly well.

The Marineland Portrait Glass LED Aquarium Kit is a 5-gallon starter tank designed for hobbyists who want a visually impressive aquarium without dedicating a large amount of space. Its tall, portrait-style form factor makes it a natural fit for desks, bookshelves, and countertops, and the all-in-one kit format means beginners can set it up without hunting for separate components.

One of the most compelling features is the dual-mode LED lighting system. Bright white LEDs simulate natural sunlight and bring out the colors of fish and plants during the day, while blue LEDs shift the mood to a calm, moonlit glow in the evening. A three-way toggle switch makes it simple to cycle between white, blue, and off settings, giving you full control over the ambiance.

The hidden 3-stage filtration system is a genuine standout. By tucking the filter out of sight, Marineland keeps the viewing panels clean and distraction-free, which is a thoughtful design choice that elevates the overall look of the tank. The adjustable flow pump is a useful addition, allowing you to dial back the current for delicate fish or increase it for better water turnover. The sliding glass canopy and hinged light panel make routine maintenance and feeding straightforward.

There are a few things to keep in mind before buying. The 5-gallon capacity, while ideal for a betta fish, small community fish, or shrimp, will feel restrictive for anyone hoping to keep a wider variety of species. A heater is not included, which is a notable omission for those planning to keep tropical fish. Additionally, the Rite-Size Z filter cartridges are proprietary and need replacing roughly every month, adding to the long-term cost of ownership.

Overall, the Marineland Portrait is a well-engineered, attractive aquarium kit that delivers on both form and function. It is particularly well suited for first-time fish keepers, office environments, or anyone who wants a statement piece that is easy to maintain. With its strong brand heritage and thoughtful feature set, it earns its place as one of the top-ranked starter kits in its category.

If you are considering the Marineland Portrait as your first aquarium, it is one of the most beginner-friendly options available. The kit format removes much of the guesswork involved in sourcing compatible equipment, and the hidden filtration and LED lighting are ready to use right out of the box. However, there are a few additional items you should plan to purchase to complete your setup.

A submersible heater is essential if you plan to keep tropical fish such as bettas, guppies, or tetras, all of which thrive at temperatures between 76 and 82 degrees Fahrenheit. Marineland recommends the Tetra HT Submersible Aquarium Heater, which is sized appropriately for tanks in the 2 to 10 gallon range. You will also want a water conditioner to neutralize chlorine and chloramines from tap water before adding fish.

For stocking, a single betta fish is the most popular choice for a 5-gallon portrait tank and thrives in the calmer water flow this filter provides. Alternatively, a small colony of neocaridina shrimp or a group of nano fish such as ember tetras or chili rasboras can make for a vibrant display. Avoid overstocking, as the smaller volume means water quality can decline quickly with too many inhabitants.

Plan to change the Rite-Size Z filter cartridge every two to four weeks for optimal water clarity and biological filtration. Keeping a few replacement cartridges on hand is a good habit. Performing a 25 to 30 percent water change weekly will also help maintain a healthy environment for your fish and extend the life of your equipment.

The Tetra 20 Gallon Complete Tropical Fish Tank Kit is a fully bundled aquarium starter package designed for beginners and returning hobbyists who want a straightforward, ready-to-use freshwater setup. It includes a glass aquarium, LED hood, internal power filter, heater, thermometer, water conditioner sample, fish food sample and a setup guide, covering virtually everything needed to get started except gravel and fish.

The standout feature of this kit is its filtration system. The Tetra Whisper PF20 Power Filter combines mechanical filtration to trap debris with chemical filtration via Ultra-Activated Carbon, effectively removing odors, discoloration and harmful toxins from the water. Reviewers consistently praise the filter for running quietly after the initial air purge and for producing a satisfying waterfall sound that adds to the ambiance of the tank.

Build quality is solid throughout. The glass aquarium is clear, durable and free of leaks according to the vast majority of customer reports. The low-profile hinged hood integrates LED lighting that casts a clean, natural daylight glow across the tank, making fish colors pop and giving artificial plants a surprisingly attractive appearance. The hood design includes a hinged feeding door and cutouts for filter tubing, though these openings cannot be fully sealed, which is worth noting for pet owners with cats or fish prone to jumping.

The main drawbacks are minor but worth considering. The tank proportions lean taller rather than wider, which limits horizontal swimming space for certain fish species. Additionally, gravel and extra decorations must be purchased separately to fully complete the aquascape. Some users have also noted the filter can be slightly louder than premium standalone units, though most find the noise acceptable for the price point.

Overall, the Tetra 20 Gallon Complete Kit delivers outstanding value and ease of use for anyone stepping into the freshwater fishkeeping hobby. Its comprehensive bundle, reliable filtration, attractive LED lighting and durable glass construction make it one of the best entry-level aquarium kits available at this price range. Highly recommended for beginners and casual hobbyists alike.

This kit is designed to give new fishkeepers everything they need to get their aquarium running from day one. Below is a breakdown of every component included in the box so you know exactly what you are getting before you buy.

Tank and Hood: One 20-gallon glass aquarium measuring 24.2 inches long by 12.4 inches wide by 16.7 inches high, paired with a low-profile hinged hood featuring a built-in LED lighting system and a convenient front feeding door.

Filtration: Tetra Whisper PF20 Power Filter with one Tetra Whisper Bio-Bag Filter Cartridge. The filter uses both mechanical and chemical filtration with Ultra-Activated Carbon to keep water clean, clear and odor-free.

Heating and Monitoring: An aquarium heater to maintain a stable tropical water temperature, plus a thermometer so you can monitor conditions at a glance.

Starter Supplies: A sample of AquaSafe water conditioner to neutralize tap water, a sample of TetraMin fish food to get you started, and a detailed setup and maintenance guide. Decorative artificial plants are also included to give the tank an instant natural look. Note that gravel and fish are not included and must be purchased separately.

If you are new to fishkeeping, a 20-gallon tank is widely considered the ideal starting size. It is large enough to maintain stable water chemistry, which makes it more forgiving for beginners, yet small enough to fit comfortably on a sturdy desk, dresser or dedicated aquarium stand. Before purchasing, make sure your chosen surface can support at least 200 pounds when the tank is filled with water, gravel and decorations.

This kit is best suited for tropical freshwater fish that thrive at temperatures between 72 and 80 degrees Fahrenheit. Popular choices for a 20-gallon setup include neon tetras, guppies, mollies, corydoras catfish, small angelfish and ghost shrimp. Avoid overstocking, as a general rule of thumb is one inch of fish per gallon of water. Always consult your local fish retailer for species compatibility advice before purchasing fish.

To complete your setup beyond what is included in the kit, you will want to purchase aquarium gravel or substrate, additional decorations or live plants, and a water testing kit to monitor ammonia, nitrite, nitrate and pH levels. Cycling your tank before adding fish is strongly recommended and typically takes two to four weeks. The included setup guide covers this process, and Tetra's product range offers compatible supplements to support the nitrogen cycle.

This kit is not recommended for saltwater or reef aquariums, as it is specifically designed for freshwater tropical environments. If you plan to keep fish that require higher water flow or specialized filtration, consider upgrading the filter down the line, though most users find the included Whisper filter more than adequate for a standard community tank at this size.

The Aqueon 10-Gallon Aquarium Starter Kit is designed for anyone stepping into the hobby for the first time, as well as experienced hobbyists who want a reliable, fuss-free secondary tank. It comes packaged with everything needed to set up a functioning freshwater or saltwater fish habitat right out of the box, including a glass aquarium, SmartClean filtration, LED hood, preset heater, thermometer, fish net, premium fish food sample, and water conditioner.

The standout feature of this kit is the SmartClean internal power filter, which streamlines one of the most tedious parts of aquarium ownership: water changes. Rather than a complicated external canister system, this compact internal filter makes routine maintenance approachable even for complete beginners. The preset 50W heater is equally impressive, locking in a steady 78 degrees Fahrenheit without any manual calibration, which is the sweet spot for popular tropical species like tetras, guppies, platies, and betta fish.

Build quality is solid throughout. The glass aquarium offers excellent optical clarity and arrives well-packaged, with reviewers consistently reporting no cracks or missing components. The low-profile LED hood delivers bright, cool white light that makes fish colors pop and gives the tank a clean, modern look. The integrated feeding door is a small but genuinely useful detail that saves time during daily care routines.

There are a few things to be aware of before purchasing. The filter output can create a noticeable current if the tank is not filled to the recommended water level, which may not suit very slow-moving fish without some adjustment. A small number of buyers have also pointed out that the silicone sealing along the tank edges is not the neatest cosmetically, though it does not affect the structural integrity or waterproofing of the tank.

Overall, the Aqueon 10-Gallon Starter Kit delivers strong value for its price point, combining practical design, reliable components, and genuine ease of use. It earns its place as one of the top-ranked aquarium starter kits available, and is a confident recommendation for anyone ready to bring aquatic life into their home.

This kit is designed so that buyers do not need to purchase any additional equipment to get started. Every component needed for a healthy aquatic setup is included in the box, carefully selected by Aqueon to work together as a cohesive system.

The package contains: a 10-gallon glass rectangle aquarium, a low-profile hood with cool white LED lighting and a feeding door, a SmartClean internal power filter (small), a medium EcoRenew filter cartridge, a submersible preset heater rated at 50W, a stick-on thermometer, a fish net, a premium fish food sample, and a water conditioner sample. A printed setup guide is also included to walk new owners through the entire process step by step.

The EcoRenew cartridge is worth highlighting as an eco-conscious choice. It is designed to be rinsed and reused rather than replaced as frequently as traditional cartridges, which reduces ongoing maintenance costs and environmental impact over time. Replacement cartridges are widely available through Aqueon and major retailers.

Choosing the right starter aquarium comes down to three key factors: the fish species you want to keep, the space available in your home, and how much ongoing maintenance you are willing to commit to. The Aqueon 10-Gallon Kit is a strong choice for small tropical fish communities, but it helps to understand what it is and is not suited for before buying.

This tank works best for species that thrive in groups and stay relatively small, such as neon tetras, ember tetras, guppies, platies, mollies, and a single betta fish. A 10-gallon tank is not recommended for goldfish, which require a minimum of 20 gallons, or for cichlids and other territorial species that need more territory. If you are planning a community tank, aim for no more than 10 small fish to avoid overcrowding.

If you want more stocking flexibility, Aqueon also offers this same kit in a 20-gallon version, which opens up a wider range of species and allows for larger community setups. For those interested in saltwater, this kit is usable for a simple fish-only saltwater tank with live rock, though it is not suited for reef systems with corals due to the basic lighting. Plan to invest in additional saltwater-specific supplies such as a hydrometer, marine salt mix, and a protein skimmer if going that route.

The Wonderfactory 10-gallon glass aquarium kit is a complete freshwater starter setup designed for beginners, gift recipients, and hobbyists who want everything in one box. It includes the rimless glass tank, a hang-on-back filter with media, an adjustable heater, an LED light, and a 5-in-1 cleaning tool set, making it one of the most fully equipped entry-level kits available at this price point.

The standout feature is the ultra-clear 4mm HD glass with 92% light transmittance, which provides a genuinely distortion-free view that rivals tanks costing significantly more. The inclusion of a heater is a meaningful differentiator, as it opens the door to tropical species like bettas and zebra danios that require stable water temperatures, something most competing starter kits simply do not offer.

Filtration is handled by a hang-on-back system with dual-stage media: a mechanical sponge layer captures visible debris while ceramic rings support beneficial bacteria colonies for biological toxin removal. This setup actively promotes oxygen exchange and water clarity, reducing the maintenance burden for new fishkeepers. The pre-glued soft base mat is a thoughtful touch that protects furniture and dampens vibration noise.

There are a few things worth noting before purchasing. The manufacturer acknowledges that filter packaging may reflect an older version, so buyers should refer to the actual product received rather than the box imagery. The filter also lacks an oil film skimmer, which could be a minor inconvenience for tanks prone to surface film. As a newly listed product, there is currently no independent buyer feedback to confirm long-term seal integrity or heater reliability under daily use.

Overall, the Wonderfactory 10-gallon kit is a compelling, well-rounded option for anyone entering the aquarium hobby or looking for a thoughtful gift. The combination of premium glass clarity, included heating, and dual-stage filtration at this price is genuinely hard to beat. With responsive customer support and a clean rimless design, it earns a confident recommendation for beginners and casual hobbyists alike.

If you are setting up your first aquarium, the Wonderfactory 10-gallon kit removes the guesswork by providing every essential component in a single purchase. Before adding fish, allow the tank to cycle for at least two to four weeks so beneficial bacteria can establish in the filter media, which will protect your fish from harmful ammonia spikes.

For stocking recommendations, zebra danios are an excellent first fish as they are hardy, adaptable, and thrive in newly cycled tanks. Betta fish are also well-suited to this tank size, though bettas should generally be kept alone or with carefully selected, peaceful tank mates. Avoid overstocking: a good general rule for freshwater fish is one inch of fish per gallon of water.

Maintenance is straightforward with this setup. Replace approximately 20% of the water monthly to dilute waste and replenish minerals. Rinse filter sponge media in removed tank water (never tap water) to preserve beneficial bacteria. Limit lighting to 3 to 4 hours per day to prevent algae overgrowth, and keep the tank away from direct sunlight for the same reason.

When using the heater, always ensure it is fully submerged before plugging it in, and allow it to cool for 10 to 20 minutes before removing it for water changes or cleaning. Do not bury the heater in sand or gravel substrate, and maintain at least 2 inches of clearance from the water surface. Following these steps will extend the life of your equipment and keep your fish safe.

The GloFish 20-Gallon Glass Aquarium Kit is a complete starter package aimed at both first-time fish keepers and experienced hobbyists who want a visually striking, low-maintenance setup. It is especially well-suited for anyone keeping GloFish fluorescent fish and looking to showcase them in a modern, living-room-worthy display. The kit ships with nearly everything needed to get started, including filtration, lighting, a glass canopy, and a fish net.

The standout feature is the seamless, curved glass front panel, which provides a wide, distortion-free view of the tank interior. Combined with the three-mode LED light stick offering white, blue, and magenta settings, the visual impact is genuinely impressive. Reviewers consistently note that the tank draws compliments from guests, and the lighting does an exceptional job of making fluorescent fish colors come alive in any room.

Build quality is solid for the price point. The glass construction feels premium compared to acrylic alternatives, and the integrated back panel that hides the filter and heater compartment gives the exterior a clean, minimalist appearance. The flip-up hood and sliding canopy are functional, though some users find the canopy slightly unstable during feeding, which is worth noting for households with children or frequent feeders.

There are a few honest drawbacks to consider. A handful of buyers have reported a minor leak at the front left corner of the lid, which appears to be a recurring issue worth watching after setup. The heater is also not included despite the back panel being designed to house one, meaning an additional purchase is necessary for tropical or temperature-sensitive species. Customer service experiences have been mixed based on the available reviews.

Overall, the GloFish 20-Gallon Glass Aquarium Kit delivers a premium aesthetic and a genuinely beginner-friendly experience at a mid-range price. The curved glass design, integrated filtration, and versatile LED system make it one of the more attractive all-in-one kits available in this size category. For buyers who prioritize style and ease of setup, and who plan to keep GloFish or similarly vibrant species, this tank is a compelling and well-rounded choice.

Model Number: AQ-78451
UPC: 046798784517
Style: Modern
Intended Use: Indoor freshwater aquarium for GloFish fluorescent fish and compatible species

If you are new to fishkeeping, the GloFish 20-Gallon Kit is one of the more forgiving starter options available. The 20-gallon size is a sweet spot for beginners because larger water volumes are more stable chemically, meaning small mistakes with feeding or water changes are less likely to harm your fish. Smaller tanks, while cheaper, can experience rapid water quality swings that are harder to manage.

This tank is optimized for GloFish fluorescent species such as Danios, Tetras, Barbs, and Bettas, all of which thrive under the blue and magenta LED settings included. If you plan to keep tropical fish that require a heater, budget for a separate submersible heater rated for 20 gallons, as one is not included in the kit. The back panel compartment is designed to accommodate a standard slim heater neatly out of sight.

For the best overall setup, consider pairing this tank with the dedicated GloFish 20-Gallon Stand, which is designed with matching rounded corners to complement the curved glass profile. Also plan for a water conditioner, a thermometer, and a water testing kit as essential accessories to complete your fishkeeping toolkit. Cycling the tank for two to four weeks before adding fish is strongly recommended to establish healthy beneficial bacteria in the filter media.

The hygger Horizon 8 Gallon LED Glass Aquarium Kit is a thoughtfully designed all-in-one starter package aimed at new hobbyists and anyone who wants a visually striking tank without the complexity of sourcing components separately. It suits bettas, small community fish over 2 inches, shrimp, and even small turtles, and works in both freshwater and saltwater environments. The compact footprint makes it equally at home on an office desk or a living room shelf.

The standout feature is the convex arc curved front glass, which widens the viewing angle noticeably compared to flat-panel tanks and gives the aquarium a modern, almost gallery-like presence. The 18W LED light is genuinely versatile, offering five brightness steps and three color modes controlled by an external digital timer, so you can simulate natural daylight for plant growth during the day and shift to atmospheric blue or red hues at night. The 7W two-stage power filter runs quietly and keeps water clear, with adjustable flow and two rain shower tubes that soften surface agitation and reduce noise further.

Build quality is solid throughout. The 5mm ultra-transparent glass panels are joined with non-toxic glue and reinforced black plastic rims, and the tank arrived well-protected thanks to triple-layer foam packaging. The handcrafted resin 3D rockery background is detailed and realistic, adding genuine visual depth without any extra cost or effort. The LED light housing is sealed with waterproof glue, and the brackets are sturdy and adjustable up to 19 inches, so the light can even be repurposed on a different tank later.

There are a few practical considerations worth noting. The filter is powerful relative to the tank size, and the manufacturer explicitly warns against keeping fish shorter than 2 inches when the filter is running. The 3D background is permanently bonded to the rear panel, so aquascapers who prefer a blank canvas will find this limiting. Additionally, the tank has no lid, which means evaporation is higher and jumping fish could be a concern for certain species.

Overall, the hygger Horizon 8 Gallon Kit delivers excellent value for a beginner or casual hobbyist who wants a complete, attractive setup with minimal fuss. The curved glass design, programmable lighting, and integrated 3D background give it a premium look that punches above its price point. As long as you stock it with appropriately sized inhabitants and place it on a surface that can handle nearly 70 pounds when full, this kit is a genuinely rewarding first aquarium experience.

Tank Dimensions: 19 inches L x 11.8 inches W x 9.6 inches H. Tank volume is 8 gallons total, holding approximately 6 gallons of water due to the integrated 3D background. Full weight is approximately 68 pounds. Glass thickness is 5mm.

LED Light: 18W, DC 12V / 1.5A input (AC 100-240V adapter included). Three color modes: white, blue/white/red, red/blue. Five brightness levels from 10% to 100%. Programmable timer: 3, 6, or 12 hours. Adjustable mounting brackets extend from 0 to 19 inches. Rated lifespan up to 20,000 hours.

Power Filter Pump: 7W, 110 GPH flow rate. US plug, 110-120V / 60Hz. Two-stage filtration (mechanical floss and activated carbon). Supports vertical and horizontal installation. Suitable for tanks from 2 to 8 gallons. Minimum water depth: 2.5 inches. Cable length: 4.3 feet.

3D Background Decor: Made from non-toxic resin, permanently fixed to the rear panel with waterproof glue. Lightweight and handcrafted with fine detail. Compatible with live plants on the rockery surface. Model number: HGH906. Warranty: 1 year.

If you are new to fishkeeping, the hygger Horizon 8 Gallon Kit removes most of the guesswork from getting started. Everything you need for a basic setup is included, but you will still need to purchase fish, water conditioner, a thermometer, a heater if keeping tropical species, and substrate such as gravel or sand (at least 3 pounds to cover the bottom). Budget for these extras before purchase.

Fish selection matters with this tank. The filter is rated at 110 GPH, which is a strong flow for an 8-gallon tank. Stick to fish that are at least 2 inches long and prefer moderate to strong current, or reduce the flow using the adjustable knob. A single betta is an excellent choice since bettas are hardy, visually striking, and do not require a heater in most room-temperature environments. Small schools of nano fish like ember tetras or chili rasboras also work well once the tank is properly cycled.

Before adding any livestock, run the filter for at least 24 hours and cycle the tank to establish beneficial bacteria. This process typically takes 4 to 6 weeks using the fishless cycling method with ammonia, or 2 to 4 weeks with a bacterial starter product. Skipping this step is the most common mistake beginners make and leads to unhealthy water conditions. The programmable LED timer is a helpful tool during cycling as consistent lighting encourages beneficial bacterial colonies.

Placement is important. Choose a flat, sturdy surface away from direct sunlight to prevent algae overgrowth and temperature swings. The tank has no lid, so keep it away from curious pets and ensure the surface can comfortably support close to 70 pounds. A rubber mat under the tank adds grip and protects furniture. Because there is no cover, top off evaporated water every few days to keep the filter intake submerged and functioning correctly.
