Hi,
Well for softies, 100 watts of pc lighting would be fine, that is what I use and haven't had a problem with any corals yet. If you are thinking of SPS, then MH is the only way to go, maybe someone can offer more advise on that one.
Hey Conch - - - - I noticed where you have 2 50/50 pc lights, do you think the look is better than standard 1 and 1 light combo? Also, how do you control the dusk/dawn biz having the 50/50 combos??? just wondering, thanks
