Aquacity Aquapapa Bio Sponge Filter 20 or 40 Gal Breeding Fry Betta Shrimp Fish Tank Aquarium (Ship from CA USA) (Air Tubing Kit)

Im literally never going back to any other type of filter

Perfect for my small tanks!

Excellent product worth the money I have it set up in a 20gallon breeders tank. The fry are safe with this filter

These are great for the price! Im very pleased with the performance of the filters

Excellent product ty

Nice product. Works as expected.

I needed a filter that would work well in a lower water level since this is in a tank set up for Fiddler crabs. While the water level still cannot be quite as low as I would like it, this has worked out much better than the larger filter we originally had in the tank. It catches all the loose food that can float around in there and the crabs seem to enjoy picking off of it to eat. The crabs are happy, so we are happy. I am still on the lookout for a smaller filter but this one is great for the time being.

Sponge filters have many uses and can be connected to overhang filters or be a stand alone filter as well. Sponge filters are much easier to clean as well as being able to breed your fish without any problems for the fry or baby shrimps to get sucked into an overhang filter.

Was actually large and its working well in my axoloti tank

Didnt love it. Actually replaced it. Used in a 20 gallon long. Majority of community is African Dwarf Frogs, one Beta, one Pleco. Tank was constantly cloudy, Frogs liked hiding in the folds too so have to be careful with smaller critters.
