Lighting choice

I'd vote for either a 6-8 (10 if ur budget allows) bulb T5 unit or a 250W MH/T5 combo unit
 
MH/VHO combo is much better than MH/T5 IMO...with MH/T5 I could barely notice the T5s because the MH was much more powerful.
 
i'm trying not to use a chiller to keep the electric bill down.


I have 2 250watts over my 90 and I never need a chiller, I have the opposite problem, right now I have 2 - 300W heaters that kick on farely often to keep the water at 79.

In the summer the heaters dont kick on but at night, and durring the day I have a clip on fan above my sump that keeps my water below 81.
