I built my canopy today for my new MH. the canopy is going on a 75gal reef tank. my question is, I made the canopy 1'11" high. I did alot of research. and everyone said to keep the MH, atleast 8" off the water, so I figured I whould keep them at 12" off. the other reason I made it so high was for tempature reason's. rather than spending 4-5 houndred dollors on a chiller in a couple of months I figured I whould just make it taller to add more room for air to circulate. is this alright, or do you think that I just created more problems for myself. the MH are 175w. thanks for any help
