I've always used eheim classic 2213, 2215, 2217 or fluval 404's on my tanks.
I'm after a canister filter for my new 300 litre tank, but filter needs to be rated for at least 400 litre tank.
What do you use, what's good and what's bad?
I've seen the aqua one aquis filters around, how reliable are they, and how quiet?
