As water is drawn out through the lift tube or pump, it is replaced by water entering the sponge. The sponge is a mechanical filter and the surface of all the bubbles or pockets in the sponge provide a bed for the bacteria of a biological filter. The bacteria help to break down harmful waste (ammonia and nitrite). Sponge filters provide both mechanical and biological filtration. Most sponge filters are reasonably efficient filters for small volume tanks. These filter are 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. Also, the air infusion chamber produces minute bubbles which increase the oxygen solubility. Review: Perfect for bettas - For the purpose I am using them for (many betta tanks ran by a single air pump), these are PERFECT. Running 8 of these on a large air pump is substantially more cost effective than running 8 individual power filters. The bettas also enjoy that there is less turbulence in their tanks. As a few other people mentioned, they are somewhat larger than I had pictured in my head but that is perfect... more surface area for beneficial bacteria growth. Review: Works really well - I got this 4 pack and the single ones. But this is better. The single order one has only one suction cup. This has two. Also this one produces more bubbles and easier to adjust than the single order one. Theyre really different. ## Features - Good for both fresh and salt water tank. - Measurement: 5.0”L x 1.8”W x 5.5”H. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #472,473 in Pet Supplies ( See Top 100 in Pet Supplies ) #1,968 in Aquarium Filters | | Customer Reviews | 4.3 out of 5 stars 45 Reviews | ## Images ![(Ship from USA) Aquapapa 4X Bio Sponge Filter Betta Fry Aquarium Fish Tank Double Sponge (S) XY-2831 .ITEM-NO/EGB41S-1GFT10832 - Image 1](https://m.media-amazon.com/images/I/81aE6r70fGL.jpg) ![(Ship from USA) Aquapapa 4X Bio Sponge Filter Betta Fry Aquarium Fish Tank Double Sponge (S) XY-2831 .ITEM-NO/EGB41S-1GFT10832 - Image 2](https://m.media-amazon.com/images/I/51-i5Bfw45L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for bettas *by L***N on September 19, 2017* For the purpose I am using them for (many betta tanks ran by a single air pump), these are PERFECT.

But this is better. The single order one has only one suction cup. This has two. Also this one produces more bubbles and easier to adjust than the single order one. Theyre really different. ### ⭐⭐⭐⭐⭐ I love the extra biological filtration they provide *by A***W on March 15, 2018* I have the four divided amongst three different tanks. Two are in my 10 gallon quarantine tank. And one is in my 55 gallon platy and betta tank. And the last in my general community tank with amano shrimp, tetras, and Corydoras. I love the extra biological filtration they provide. The two in 55 gallon tanks aren’t the only filtration I use but are more of a extra help to a HOB and canister filter. The fish love it because usually extra food will get stuck to the side and the shrimp hang out eating the dretitus that build up in between tank cleaning. They are excellent for fry care in that there is no chance it can get sucked into the filter like other means of filtration and they keep the water surface moving to help with the gas exchange necessary for aquariums. It also isn’t too strang and my betta hangs out around it with ease. --- ## 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/30678160-ship-from-usa-aquapapa-4x-bio-sponge-filter-betta-fry](https://www.desertcart.co.za/products/30678160-ship-from-usa-aquapapa-4x-bio-sponge-filter-betta-fry) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-18*
