This filter works perfectly for my 8-gallon breeding tank. I added a small sponge and floss, and the water stays clear. It’s simple to set up and clean every two weeks. Great for small tanks where quiet operation is important.

I used it in a 10-gallon tank with a breeding setup. The floss helps keep the water clean, and I can easily add new media when needed. The only downside is that it requires a small air pump, but that’s a minor trade-off.

Very reliable and quiet. I’ve used it for several months now and haven’t had any issues with clogging or performance. The corner design fits well in my tank setup and doesn’t take up much space.
