Canopy and lighting
I have a question about MH distance down to the water level. I belive i have been told by others that 9-10" of height to the water surface. The problem i think i will have is that the inside lid of my canopy to the top of the trim on the tank is 13.5" . Will this be to low for a 2x250w mogul retro fit? It would put me at somewhere about 8.5" from the MH bulb to the top trim on the tank. is this too close? I am just guessing the retros will be about 5" in height once screwed to the inside lid of the canopy.
Is this to close to the water?
Or maybe it will work since the water level will be about a 1/2 to 1" below the top of the tank.

Casey,
You run SE bulbs right? no splash guards?
Do you have your reflectors screwed right into the lid?

I hate to be a pain and sound like a noob, but how hot does the top of your canopy get? I am just worried about it catching on fire or something

The wood I used when I made my canopy is 1/2" thick and it only gets warm on the top
doesnt worry me at all.

If i use spacers that is going to cut down my height from the lamps to the water. I am pretty close to being at minimal height as it is.
