I'm pretty new to this and was wondering how I should set up my flow. I have a aquatop cf300 canister rated at 275 gph, koralia 550, and a koralia 240 nano power heads. I just steeped up to this marineland 27 gallon cube from a 10 gallon and am having some troubles. Any feedback would be great. Also suggestions on my filter set up I'm running the provided pads then some carbon then filter floss followed by a phosphor absorbent pad. And finally I have a kessil a150 sky blue 6 inches from the waterline and would like to add an actinic for a deeper blue...please help I'm heading to the Lfs in the morning.
