another quick question for anyone who has an answer, im wanting to get rid of my power compact lights and upgrade to T5 so i found a system i want just not sure how many watts i should get , either one with 6 bulbs at 39 watts a piece or the system with 8 bulbs at39 watts. the 6x39 will give me 234 watts wich is about 6.2 watts per gallon in my tank or the 8x39 wich would be 312 watts at 8.2 watts per gallon. I know it depends on what i plan on keeping, and where they are placed, just want to know which one would look the best without bleaching my corals
