Aquaneat Aquarium Corner Sponge Filter, Air Driven, for Fish Tank up to 20 Gallon

It functions like a songe filter. Adding the choice of media is why it's a better filter than a sponge alone. Easy to clean, and operates with air.

Couldnt be pleased more. Comes filled with materials ready for filtration. Most substantial bubble ever.

I have a 10 gallon tank with a very dirty goldfish. I ordered the bigger one, but it doesn’t fit in the tank right so I separated the two pieces and made one. It seems to do the job. I’m not disappointed

I really like this filter. it cleaned up my 20 gal. tank in about 20 minutes. very satisfied

Easy to clean in turtle aquarium

Shipped fast! Small and works amazing!!

I only said i wouldn’t recommend because it DOES NOT COME WITH AIR PUMP. That i guess you have to buy separately, but you get the hose for it? Makes no sense.

Unusable. Came in a box that wasn't packaged correctly, came out of the box smashed. There was nothing no packing material like bubble wrap. box was the exact fit and was crushed on the bottom of the package.

I thought that this was all I needed for the tank turns out I need an air pump I was trying to figure out how to get it to work then my daughters boyfriend said you need an air pump so I am ordering an air pump now lol it’s always something !!! Sure wish they would say it in the ad that way I could’ve purchased it together with the filter

missing parts no assembly instructions. I would give zero stars but there isnt a zero
