How high do I want my lighting from my tank? Its 5 inches from the tank now and I can't keep the temp below 80. I have to unplug my heater during the day to keep it at 80. Should I move it up a few more inches? I have 150w and 2 64w tubes.

MIne is 5-6" from the water and the only time I use my heater is now because its winter here and cold so my tank would be around 75 degrees.

Sounds like a heater malfunction. Seriously it's clear as day. If you have it set to come on at anything below 76F and to shut off at 79 but it's coming on at 80 and staying on the warmer it gets, there is a problem right? Unplug it. I never use one with the reef.

set the heater at the desired temperature u want it, it will only kick in if it goes below ur set suitable temperature. i have question on lighting aswell, is there a differance between metal halide and just halide lights? or do u guys in american just call them metal halides cause i can get halide lights dirt cheap through my work + fitting just want to know if they were the same...

If you are a serious reefer you have serious lighting, So the heat from the lights will keep the water cool. I dont use a heater except for right now to keep my water temp right though out the night seeing how it still gets cold here. In the summer or when the temp stay's the same I will be removing mine till next winter.

When I lived down south my tank never dropped below 80 degrees. It all depends were you live, if you should/should not have a heater. Here in maryland now my tank has diped to 74 degrees over night. Thats why I put the heater back in the sump for now. Its not the fish that mind its the corals that care.
