Hi all,
I have a 400W MH bulb mounted about 8-in above the water surface in my 55gal reef. The water temperature goes way up when it's running (the bulb is cooled by 4 computer fans, so that temp doesn't get too high). Currently I cover the aquarium with glass, about 2-in above the water surface, but I am thinking of removing this and putting in a fan to cool the water.
The question is, should I put in additional glass/acrylic between the bulb and the water surface (say, closer to the bulb)? Is it dangerous to expose the lighting components (bulb and mount) to the evaporate in general?
The aquarium is covered by a full hood made of black acrylic. How does one deal with heat and evaporate transfer out of the hood? Venting fans, drilling holes, nothing, etc?
Thanks for advice!
