Probably quite a bit because your most likely going to need a chiller.
As Brad said you might have a heat issue.

If I blow a big Fan across the water and the mh is 10 inches above the tank u think ill still need a chiller? If I need a chiller there goes that idea

I have never had a chiller on smaller tanks with halides, and have never had temperature issues at all. It all depends on your house temp. If it fluctuates a lot and gets super hot in the summer time, you will have problems for sure.

My house luckily stays constant enough to avoid any temp swings.

That would work fine. But house temp will make a big difference. I know you guys in BC get pretty darn hot out there.

My house does get fairly hot in the summer, I think I'm going to wait until summers over to put this thing on my tank. That will give me enough time to get an air conditiner going in my room where the tank is before next summer. Damn I hate waiting

Oh man I hooked the halide up and put it over the tank for a few minutes its like 5 times the light I've got now and it was 14" above the tank. But it defiantly will get hot on a summer day. Love the look of it though

My tank is packed full of softies, now how do I acclimate them to the light? Just hang it way up high and lower it as time goes by?
