Hi everyone,

I would like some opinions or possible suggestions.

I have a 40 gal tall 22" height aquarium. My question is regards to lighting. I have two 175 watt MH fixtures laying around that I would like to install on this tank with maybe 2 t5 retrokits for actinics. I also have a 1/5 hp chiller which will be installed as well. The canopy will allow the mh bulbs to be 6" from the surface of the water. I will have 2 4" fans on the back and a 3" fan on the side. I would like to know if I am crazy in putting this much light on the tank and is it even possible in regards to heat, wattage, or light output to the corals? I also have a piece of plastic which extends from the front to back in the middle of the tank and that is the reason for 2 MH instead of one.
Any thoughts are most appreciated.

Thanks,
Norman
