I had read about how sponge filters were a good option for bettas as they provide a more gentle flow compared to HOB filters as well as helping to oxygenate the water. After watching a video explaining how to use sponge filters, I knew to get an air pump beforehand with an air stone, it was a bit tricky fitting the air stone inside the filter but I followed the directions on the tutorial video I had watched and figured it out. I’ve only used it in my betta’s tank for about a couple of weeks now but it’s already made such a difference with the water clarity, before it was always a little cloudy but now it’s crystal clear. I decided to clean out the sponge while siphoning the tank yesterday and so much gunk came out after the short amount of time of being the tank. I also love that not only do I no longer have to buy new filter cartridges every month, I probably won’t have to replace this sponge filter for a very long time (til it falls apart anyway). I never thought such a cheap and simple filter would outperform the larger, more expensive filters. Review: Okay quality. Good filtration. - Great product for the price. Filters my tanks well. It is a bit cheaply made tho, I had one them brake apart but I’m not mad for how cheap they are. Good size as well, easy to hide. ## Features - Sponge filter provide both mechanical and bio filtration, also, the air infusion chamber produces minute bubbles which increase the oxygen solubility - Safe for fish: soft sponge material, traps floating debris and won't suck up your fish - 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 20 gallon, excellent for small size fish like betta, dwarf cichlid, guppy, killifish etc., or for hatcheries, maternity tanks, nano tanks and fry tanks, as the filter produces minimal current and has almost no way to suck the fish through the filter - Includes: 3pcs of sponge filter; Dimension: 3.0"D X 6.5"H ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.7 out of 5 stars 3,437 Reviews | ## Images ![AQUANEAT Aquarium Bio Sponge Filter Breeding Fry Betta Shrimp Nano Fish Tank,3pcs (Middle up to 20Gal) - Image 1](https://m.media-amazon.com/images/I/71McL-SjwLL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The best aquarium filter I’ve used *by S***. on August 8, 2026* I’ve tried various aquarium filters over the years but have never really been impressed with any of them til now.

Filters my tanks well. It is a bit cheaply made tho, I had one them brake apart but I’m not mad for how cheap they are. Good size as well, easy to hide. ### ⭐⭐⭐⭐⭐ Great sponge filters *by R***N on August 11, 2026* I use these as emergency filters, I added one to two of my tanks so I always have an emergency filter to put in an isolation or emergency tank, it’s been super helpful. They aren’t huge so they work to do the job and not take over the tank, I love sponge filters because I keep shrimp. It kept my last emergency tank alive since this time I had them on the go, I can’t say if right out of the package they would have helped, but if you give them time they do wonders. --- ## 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/440081215-aquaneat-aquarium-bio-sponge-filter-breeding-fry-betta-shrimp-nano](https://www.desertcart.jp/products/440081215-aquaneat-aquarium-bio-sponge-filter-breeding-fry-betta-shrimp-nano) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-20*
