Lighting for 72 gallon Bowfront/20 gallon sump

[Canuckgod420]

I have the bow front 72...and I would never give up my 2 MH 250watt bulbs, great light output....plus I grow SPS on the bottom of the tank.
Heat has been eliminated with 2 small 4" fans, no problems.

P.S
I even have a completely sealed hood over my tank.....the 2 fans make quick work of the heat. I do have a chiller but its not even plugged in during the winter months....I of course have to use it in the summer when the room is over 90 degrees.
