I bought 75 gal, but i noticed it has a center brace, so would i buy two 24in light fixtures or 1 48in. If i buy the 48 would i have a dark spot right in the middle?
Yeah that's definitely a consideration. But NYC, I think that generally people go with the 48" light. Probably because it's less clutter.. I think the more important question you have to decide is whether you're going to go with T5's of MH's... What do you plan on keeping in your tank?
