"I've been keeping fish for a long time and have gone through many different filter brands. AquaClears are my favorites, by far. I use one for almost every tank including my marine aquarium.
They are quiet, easy to take apart and put back together, and offer complete filtration...biological, chemical, and mechanical.
It's almost like having a canister filter but smaller and cheaper.
Attached is an old picture of my marine hermit crab, Big Red. The tank has been running with an AquaClear for over a year."
