Review on Powkoo Aquarium Sponge Filter 90063 M by Pamela Begay

I have this in a nano aquarium so this filter turned out to be a bit larger than I expected/hoped for my application. I think the measurements are accurate. It's just hard to get a really good idea until you get your hands on it and put it in the aquarium. Otherwise it works fine. I like the larger bubbles it releases (if you like small airstone bubbles this might not be for you unless you want to try putting an airstone in) and the filter material does the job well.
