Hi i am in the process of transferring my newly aquired "used" 46 gallon SW set up into my 90gallon previously freshwater tank. I have been by the LFS a few times to price out equipment and am i little naive when it comes to lighting. Previously my 90 gallon had 2 x 30 watt 36 inch flourescents, which i thought was lots (lol). Now i understand for a reef tank i need 3 watts per gallon. so i am looking at about 270 watts, The LFS has suggested a "power compact" 36 inch strip that goes for about $400.00. Is that a fair price? are there other better options for around the same amount? Some of the threads i have read here have a negative spin on PC lights? what should i be looking for?
