Thank you for your prompt replies. I am going to make up a system to fit in with the MH
's so that it can come on half an hour before lights out, and stay on for half an hour after. Just a plain blue bulb should work, shouldn't it? It's just to give the appearance of dusk. I can't fit my PC
in with my MH
hood. (Too small of a hood). So I thought if I went to a small 15 watt blue incandescent, it should work. What's your thoughts on that...
Also, thanks for warning me about the top, I've got a complete glass cover, but never hurts to know when your fish are prone to long jumping.
