Sponge Filter Aquarium Air Filter Bio Filter Sponge Betta Shrimp Fry Fish Tank Sponge Filter

Sponges need replacing after a while but easy to install and easier to clean

First sponge filter and im impressed with it. Almost as good as a ‘polishing’ filter. Debris stays in place. Haven’t had to clean it yet but happy over all and so are the fry!

Great filter for money, does what's expected. My only criticism is there isn't room for an air stone without modifications but for the price, I can't complain about it

Great sponge for the tank I have (which has snails and shrimp), Easy to clean BUT it did keep floating on the first day, I just wedged it down with a piece of flat slate and all it stayed down.

Needed a corner sponge in a hurry and this fit the bill. It did float but really only needs a short time to soak then a good squeeze sorts it out, it's been fine since. The bottom is weighted although not particularly heavy. My only concern is the fish like to swim behind it and get stuck but that might be an issue with my fish more than the sponge.

This turned up without the clear tube. This was the last one too so I can’t be sent a replacement

Great item.fits perfectly in my fry tank.just the right aeration, virtually silent with small airpump.would reccomend fully.

Ein tolles produkt,

沈める時は、しっかりスポンジに水を染み込ませないと沈みません。
