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

Does the job

This is my first sponge filter. Easy to install. No issues at this point. Fast shipping.

As described. Great price, fast shipping.

Works fantastic keeps the water clean and keeps the good bacteria in the tank

I picked this up because I need a filter that wasnt going to push around my betta. Fortunately this filter is gentle and my betta has no problem swimming everywhere in the tank (even around and next to the filter!) I was concerned about how big it would look in my tank but its about the same size as an internal filter and it replaces air stones so I figured in the end its saving me space.

A little smaller than I thought but still good

Works good

This product is pretty good! The size is nice and fits quite well in a 10 gallon tank! Be aware that it only comes with the base (sponge) and the tube (as the picture shows). You will have to separately buy an air pump to go with it. It gives off plenty of oxygen and bubbles. You and your fish should be happy with this product :) I also used it for my mud-puppy (a tiger salamander in larval form), and it worked wonderfully for him. I also recommend this filter for baby fish or axolotls/mud-puppies because it is gentle and not very rough (making it easier on the animal). Hope this helps!

For a 10-20 gallon filter, these are a bit large. Theyre the size of a babys head. They would take up quite a bit of real estate in a smaller tank. Theres nothing wrong with them, they appear to be completely normal sponge filters, just huge. I have to wonder if this size is actually intended for a much larger tank size.

The only reason why I gave these a 3 star is because I didnt recieve the tubes that go with them. They work without them but would prefer to have them.
