MH, VHO heating

[gbeef]

sounds good.
my new setup is going to the basment. Heres the specs my new setup.

100Gal 60" x 18" 20"
Planning on 1X250Mh & 175Mh reason why im going with 2 different ballast is so i can keep softies and LPS. Also i would like to keep high demanding coral on one side of the tank and lower demanding coral on the other.

I plan to keep the lights off the water about 12"
Ive looked at all options for lighting the problem ive found is MH cost the same as any other option there. Except i dont want to fork out money for a chiller, that was my biggest concern.
