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

This filter is great so far! Even though I pulled out a ruler to get a visual of the size its bigger than I expected, should provide plenty of filtration for my 20 gallon long. The airline hose has a nice tight fit on the filter and after a couple days of running Ive had no issues. The box does have information and instruction in decent English. The item arrived very quickly and was well packaged for travel. I will update this if I notice any issues as Ive only had this sponge filter running for a couple days.

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.

I have these in almost all of my tanks; they take some finagling because they like to float but if you plan it right you can wedge it in behind your hardscapes so they kind of blend in and they are SO easy to set up and they provide great biofiltratioon. Easy to clean, impossibly easy to run, I have at least one in each of my tanks.

The foam is so thick and rigid that it doesnt suck much up. For that matter, Im not sure Ive seen any benefit from this sponge filter. Tried everything from low flow to a 100 gallon air pump in a 20 gallon high with no luck.

Some people call me Maurice cause I speak of the pompatus of love. Other people use this sponge filter to filter out what I say and live healthy lives.

Great product for a filter ... I use it for shrimp keeping and it gives the shrimp a place to hide and acts like a filter

Sponge filters are excellent mechanical and biological filtering devices. Currently using 2 for filtering my 75 gal tank, MAINLY as aeration, and for seeding the sponges for possible new tanks. These can be used anywhere that aeration, water movement and some bio-filtering is required.

too big. cover a lot of the fish thank

Im literally never going back to any other type of filter

Quick delivery. Works as advertised.
