I am amazed that people are only using 216w on a 75g. That's about 2.3w per gallon.
I just bought this 6 bulb unit. It's 24" long, so it uses the 24w bulbs. That gives me 144w -- or about 4.8w per gallon.
Am I going to burn my zoas, polyps and mushrooms with this unit? It sure sounds like it, if I'm reading you correctly. I plan to get some SPS and LPS soon. I'm pretty loaded with zoas and mushrooms right now.
It's a 30g tank and measures 24" deep.

I thought I was doing good. Now I'm worried that I bought too much light.
