Since I have never done a coral tank before I am unsure what specs I need for lighting.
My tank is 800 gallon,
8 ft x 4ft (front section)
7ft x 3ft ( side section)
30" depth with dual over flows.
I was talking to a guy at the lfs
and he said metal halides are the best for hard coral and from what I've read, I need 3-5 watts per gallon.
I can get metal halide 400w or 1000w fixtures really cheap but they use a tonne of electricity
I have about 10 4 ft fluorescent light fixtures that I took down from a Reno that I was Hoping to re use and change out the bulbs for t5's,
looking forward to some suggestions !
