I'm building a new canopy for my 125 and I'm going back to MH and I'm having a hard time making up my mind. I want a mixed reef, but zoas are my main stay so I don't need to be able to grow SPS on the sand . I'll use 3 MH bulbs, maybe t5s, and I definately like the blue look. Three questions:
1. What wattage for this depth, assuming I'm using a decent balast and bulb not some knock off?
2. Just 3 x 20k bulbs or 3 x 14k-15k bulbs plus t5 actinics? Why?
3. How far above the surface of the water should the bulbs be?
Answers based on experience are best
