Rena filters are usually recommened around here a lot, but with a reef, live rock would be your main source of filtration. You could fill the cannister with live rock rubble, but it is up to you. Don't know of any 54w PC
bulbs, so I guess you mean T5. If you do mean PC
, then go with T5 as it is far better than PC
due to better PAR and penetration than PC
. T5 also runs cooler and more efficient than PC
. Might recommend the Current USA Nova Extreme Pro 6x54w T5 HO
fixture. It has three actinic bulbs and 3 10k bulbs.
