On my new tank, I plan on running my halides each 6 hours a day, but not at the same time. EX.
VHO actinics - on at 9am
MH #1 - on at 11 am
MH #2 - on at 1pm
MH #1 - off at 5 pm
MH #2 - off at 7pm
VHO actinics - off at 9pm
I may adjust it so that both Halides are not cranking full force at the hottest part of the day, but you get the idea. I am also switching to electronic ballast and using 175 watt iwasaki aqua2 bulbs to get maximum par with minimal electicity and heat. I will probably still probably have to run the A/C full blast during the hottest part of the day anyway.
