My Mom has a 55Gal reef tank and we were wondering what the max lighting for her tank would be. We have 2 250W metal halides we were wanting to install in her hood but were not sure if that was going to be too much lighting for her tank. She doesn't want to get in to chillers and stuff like that but does want to do some clams and stony corals. Do you think if we had dual fans circulating the air in the hood she would be ok, or is it just too much and will cause heat issues?
