Tank Size: 10 GAL Package includes: 3 PCS of Sponge Filter How Does It Work? A sponge filter uses bubbles of air from an external air pump, or an integral water pump to draw water through the sponge. As water is drawn out through the lift tube or pump, it is replaced by water entering the sponge. The surface of all the bubbles or pockets in the sponge provides a bed for the bacteria of a biological filter. The bacteria help to break down harmful waste (ammonia and nitrite). What Maintenance Does It Require? The sponge will need to be rinsed every time it becomes dirty, about once every 2 to 4 weeks. It’s helpful to reserve the beneficial bacteria by washing the sponge gently with water from the fish tank instead of tap water. After 3 to 6 months’ usage, the micro holes of sponge is gradually clogged by the tiny debris, the beneficial bacteria won’t have as much living space as before. So it is also recommended to replace the sponge once every three to six month or when the sponge gets worn out. Review: Better than hang on back filters - I’ve been using these small sponge filters that connect to an air pump line for months, and they are just as effective as the more expensive hang-on-back (HOB) filters that pump water. These simple yet highly efficient filters provide excellent biological and mechanical filtration while maintaining gentle water flow—perfect for fish, shrimp, and fry tanks. One of the biggest advantages is their ease of maintenance. Every couple of weeks, I simply dip the sponge in dechlorinated water and squeeze it a few times to rinse out the sediment. It’s important to use chlorine-free water to avoid killing the beneficial bacteria that help keep the tank healthy. Compared to traditional HOB filters, sponge filters are **cost-effective, quiet, and reliable**. They don’t require expensive replacement cartridges, and they run smoothly as long as the air pump is functioning. They also provide great aeration, which is a bonus for oxygen-loving fish. Overall, I highly recommend these small sponge filters for **any freshwater aquarium**. Whether you’re a beginner or an experienced aquarist, they’re an affordable, low-maintenance, and highly effective alternative to pricier filtration systems. Review: It's the perfect size for my 5 gallon betta aquarium. - Great size for my 5 gallon tank. Was confused when the packaging didn't say Aquaneat on it. Instead it said Xinyou, and it had a different model number, but they are the same size and seem to be decent quality. The sponge is much thinner and coarser than the Seapora one I had in the tank, but I'm not concerned since my betta fish doesn't produce much waste, and I routinely take out uneaten food and waste after feeding him. I rinsed everything in my tap water first, and I floated the new sponge in the aquarium for 3 or 4 days before setting it up, and am leaving the sponge from his old filter in the tank for at least the rest of the week to ensure I colonize the new smaller filter sponge with the good bacteria. I never bothered modifying this filter to fit an air stone, since the inner chamber was pretty narrow and I figured the bubbles would be pretty small coming out of the upper openings. I was right...the bubbles aren't too big or loud. It might be a bigger issue if I had the air flow turned up on full power. You can see in the picture where the gravel went around the base if the old sponge filter, now it looks like a crater around the new one lol. I'm happy that Angel has more space to swim around now. ## Features - Sponge filter provide both mechanical and biological filtration, also, the air infusion chamber produces minute bubbles which increase the oxygen solubility - EASY TO SET UP & CLEAN: Simply install an airline into the unit and turn on the air pump, simply rinse and squeeze sponge in tank water - RECOMMEND TANK SIZE: Up to 10 gallon, excellent for small size fish like dwarf cichlid, guppy, killifish etc., or for hatcheries, maternity tanks, and fry tanks, as the filter produces minimal current and has almost no way to suck the fish through the filter - DIMENSION: 2.0"D X 4.75"H - INCLUDES: 3 PCS of Sponge Filter ## Technical Specifications | Specification | Value | |---------------|-------| | Pet Type | Fish and Aquatic | | Package Dimensions | 16.99 x 8.1 x 6.2 cm; 259 g | | Item model number | SF-A135x3 | | Size | Small up to 10Gal | | Quantity | 1 | | Batteries required | No | | Batteries Included | No | | Item Weight | 259 g | ## Images ![AQUANEAT 3 PCS Aquarium Bio Sponge Filter Breeding Fry Betta Shrimp Nano Fish Tank 10 Gal - Image 1](https://m.media-amazon.com/images/I/71ViR2nOuBL.jpg) ![AQUANEAT 3 PCS Aquarium Bio Sponge Filter Breeding Fry Betta Shrimp Nano Fish Tank 10 Gal - Image 2](https://m.media-amazon.com/images/I/61G+1tOIbSL.jpg) ![AQUANEAT 3 PCS Aquarium Bio Sponge Filter Breeding Fry Betta Shrimp Nano Fish Tank 10 Gal - Image 3](https://m.media-amazon.com/images/I/610E7MewSXL.jpg) ![AQUANEAT 3 PCS Aquarium Bio Sponge Filter Breeding Fry Betta Shrimp Nano Fish Tank 10 Gal - Image 4](https://m.media-amazon.com/images/I/71kWj1hqknL.jpg) ![AQUANEAT 3 PCS Aquarium Bio Sponge Filter Breeding Fry Betta Shrimp Nano Fish Tank 10 Gal - Image 5](https://m.media-amazon.com/images/I/710HWUyjo4L.jpg) ## Questions & Answers **Q: Can you add a bubble stone** A: I second cuda's response. The filter itself produces pretty large bubbles but if you have a sponge filter you dont really need an airstone unless you want it for decoration. **Q: Does it include airline tubing?** A: yes is does. it also comes with air line splits and a water drop stopper thing **Q: Anyone know where I can find 15mm OD tube to replace the riser pipe with a longer one?** A: Easy clean **Q: I am using Small up to 10gal version with 1W Bedee air pump in a 3gal water tank. I see the air bubbles, but I am not sure this filter does anything?** A: if you see bubbles it is working. i do find this filter is so small that i use 2 in my 2.5 gallon and i rinse and clean them bi weekly ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better than hang on back filters *by L***D on 2 February 2025* I’ve been using these small sponge filters that connect to an air pump line for months, and they are just as effective as the more expensive hang-on-back (HOB) filters that pump water.

The sponge foam in the photo seems coarser and more porous, while the ones I got are much less so. Functionally, it works fine as a sponge filter, but the less coarse the sponge, the more often you have to clean it. ## Frequently Bought Together - AQUANEAT 3 Pack Aquarium Bio Sponge Filter Breeding Fry Betta Shrimp Nano Fish Tank (Small up to 10Gal) - AQUANEAT LED Aquarium Light Full Spectrum for 12 Inch to 16 Inch Fish Tank Light Fresh Water - AQQA Aquarium Air Pump,3.5W 5W Dual Outlet Oxygen Pump with 2 Air Stone,Adjustable Air Valve Quiet Bubbler Pump,Up to 160 Gallon Fish Tank (3.5w) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/552636100-aquaneat-3-pcs-aquarium-bio-sponge-filter-breeding-fry-betta](https://www.desertcart.jp/products/552636100-aquaneat-3-pcs-aquarium-bio-sponge-filter-breeding-fry-betta) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-24*
