Hey guys I have one coming in a couple days from drsfostersmith.com for my 180 and I was wondering how I should set it up. It says that it should have 240 gph going through to control algae. Anyway I have a cascade 1500 canister, and a fluval fx5 running on the tank right now. The fluval is supposed to pump at 925 gph and the cascade is supposed to pump at 315 gph. Is it alright to just attach the sterilizer on the return line of the cascade? or i have a bunch of powerheads laying about if that would be a better idea. how would I set that up? thanks for the help guys!
