Review on XEOGUIYA Aquarium Ultra Quiet Oxygen Increasing Household by Morgan Arnold

I admit that paying more for this filter than a normal sponge filter is stupid, but it is much more aesthetic than standard filters, which is what I wanted. It works like a sponge filter. Other reviewers had problems. I do not know how. This is a sponge filter. It does get a bit noisy when you really turn air on it though. I'm assuming air is getting into the cap as normal sponges don't have this problem. I use them for dwarf shrimp tanks (2.5g) so I don't need a ton of sponge. That's very little. I don't think it would be useful for anything over 5g, but that's just my opinion.
