correct me if im wrong; Are power heads really necessary in a FO tank? Aside from elminating dead spots i think the output lines on my 2 canisters can substitute power heads. The only way i can see them making sense is if i use the power heads instead of airstones. I understand their purpose in a reef. I will be putting live eventually and i know this will increase dead spots. I guess i need to plan out the rock work to hide all this crap. I was thinking of using one of those rock shelves

bubbles are bad for corals. iam sure u have read that.trying to hide a power head is a great idea.get creative.some times with rocks on or around powerheads will make a chatter and thats annoying. you could also cover it with coral. buttonpolyops or greenstar coral is nice. what size is you tank again? if you have room you can make a dramatic arch drill and pin your rocks leaving a hollow spot behind rocks . for your powerheads,heaters skimmerpump ect...

good idea!! i changed my rock around in my tank a few times, i can dig up some of them so you can get a few ideas if you want?
