AQUANEAT 水槽 バイオスポンジフィルター 飼育 フライ ベタ エビ ナノ 水槽 (最大60ガロン)

Works well in a 60 and 90 gallon tank. Originally switched from a large waterfall filter to these sponge filters when the waterfall filter started getting too loud and having parts wear out from sucking up sand. Since these sponge filters don't have moving parts and uses air to filter, you don't have to worry about parts breaking, just squeeze out the sponges during water changes and occasionally take apart the plastic to clean off buildup with vinegar. Can also rinse the sponges out into other tanks to introduce microbes and waste to new systems. Recommend getting an adjustable air pump to control the level of bubbling. Works well with floating plants and water roots. The sponges started showing wear after about two years.

These are super nice. I've never used a sponge filter like this before. I have oranda goldfish in the tank I'm using this in and they absolutely love it. Their tank no longer smells "fishy". I will definitely continue using these instead of the hanging filter for these guys. They love playing in the bubbles it makes too. Very nice.

Great deal!!!

We use these to supplement an FX6 filter in our 150 gallon tank. Really it’s to keep the water crystal clear. We bought a 3 pack and a single. Hooked them to a big air pump and along with putting polyfill in the filter it keeps the water crystal clear in my tank.

After comparing, these were the largest for the price, and have a heavy base which elevate sponge portion from the floor so there is no bottom debris accumulation like I had with other sponge filters, but the best part was the sponge porous size was able to clarify the water very well and I was very surprised at just how well it filtered, plus the bubbles was nicely separated inside without the usage of any air stone. Other sponge filters I had created noisy blobs of air. These units disperse the air into smaller bubbles nicely. Just the best sponge filters I used so far.
