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

Good for my breeder tanks

Easy

the stem portion is far to small to add an air stone into it unfortunately

5 star product all-around. Recommend for a cleaner tank longer.

Works better than more fancy filters with multiple filtrations.

A little smaller than I thought but still good

Poorly made

Excellent product ty

Perfect size for a ten gallon and still leaves room for the fish

i heard that sponge filters generally use less electricity, are quieter, and are super efficient. all is true. this thing is great, i wish i knew about it before when i was on that power filter ish. this thing is great, plus my crayfish likes to use it to hide around haha.
