I currently have a 75 gallon running off of an icecap 4 bulb t5 retrofit kit. My coral's seem to be doing fine but I've been wondering if I need more light. I've been thinking of adding either another 2 bulb retrofit kit or some MH's. If I go the MH route what wattage should I use and what kalvin and how far above the water should they be? I have a 7" clearance from water to the inside of my canopy. Or will another 2 t5's be good enough. I currently have mostly LPS corals but am starting to get more into SPS. Thanks
