Hello,

Yes Kent is what I use. I used one that came with my Marineland HOT Magnum canister filter back when I knew nothing and guess what, algae all over the place.

However, I do have to build my own canister filter in order to ensure that the water flows through the media. It'll be handy but won't work until my new Dolphin pump arrives. Hahahahahaha. 3000 gph on a 20g system dude!
