ull want a light that spans it all...im afraid but money is such an issue...then again im brok and have no job and i make it somehow with my $4000 reef...lol ull manage...ur doing great so far!
The bulbs are around 24 inches long. So 4-5 inches isn't covered with them. There wasn't any options that covered the tank completely since the tank is 30" wide. We only had 200 to spend on it. Spent probably 1,500 on this tank so far. Eventually I want to move to a larger tank with a built in overflow and get some metal halide lights.
