Thank for the comments!
Not too much new progress on this tank.
Unfortunately, my Maroon Clownfish started fanning the sand with his tale and caused the left side of my rock stack to become unstable; I’ve since had to re-stack.
My light rack is working out really well. Seeing that all 3 T5 and 3 MH bulbs have reflectors, not much light at all is lost through the top. Also, because I wired in 5 4†fans turning on my lights don’t add any heat to the tank. As far as the room, I don’t think it affects the temperature, I’m sure it adds a great deal of humidity, but haven’t really measured it. My tank evaporates roughly 3 gals per day.
