The pump works well in my 35-gallon tank. The vertical design keeps the hose from kinking, and the noise is much quieter than older models. I replaced the filter pad after a few months and it still runs smoothly.

I appreciate the upright design—it makes it easy to route the hose without tangling. The rubber base does reduce noise, and the check valve prevents backflow when the power goes out.
