I am new to the forum and have a question for you guys. I am a acanaholic and I just placed the order for a 72x36x7 inch tank strictly for my acan collection, where currently I have about 200 frags and colony's covering the bottom of my display tank. My question is do you think two 24w 4bulb sunpowers will be fine? I already have one or do you think i need 6 or 8 bulb? It's a shallow tank so the lights will be mounted rather high.
