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: Good for Bettas, easy to mod, not perfect but quite good for price - First, it is a good idea to mod these to use an internal air stone. Use snips of some kind (like small side-cutters) to cut space on the inside, then attach a small air stone (0.6" cylinder worked for my "small" sized filter) inside the filter from the cap using the tubing. Doing this will make the filter create finer bubbles, providing better filtration and less water surface disturbance. It will also quiet the bubbling from the filters down quite a bit. Sponge filters are great all-round filters, and work well for fish that don't like movement (like Bettas). You need an air pump and airline tubing to use them, though. They won't flood the ground around the tank like other types of filters, and they don't really break (air pumps do, though). They are a little unsightly and harder to hide than some hang-on-back filters, but not impossible. This particular sponge filter is about as good as any other, with some caveats. Some aquarium experts recommend larger, open-cell sponges for their filters, which will clog up less than the fine closed-cell sponge on this filter. Because of this design, you will need to clean this filter more often than you otherwise might need to. It does work, though. Also, this filter is not quite weighted as much as it should be. Even when fully soaked, it's a little too buoyant. A good sponge filter should sit comfortably on the bottom of the tank. Do not ever replace the sponge, by the way. To clean it, you pull it out of the tank and squeeze it out gently in the old tank water during a water change. The sponge may last years, and will harbor beneficial bacteria for your tank. If you replace it, you will mess your tank up. To replace a filter with another, you want to run the old one alongside the new one for a least a few weeks to help the bacteria colonize the new one. 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 ### ⭐⭐⭐⭐⭐ Good for Bettas, easy to mod, not perfect but quite good for price *by C***K on 15 July 2023* First, it is a good idea to mod these to use an internal air stone.

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.co.za/products/552636100-aquaneat-3-pcs-aquarium-bio-sponge-filter-breeding-fry-betta](https://www.desertcart.co.za/products/552636100-aquaneat-3-pcs-aquarium-bio-sponge-filter-breeding-fry-betta) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-29*
