Tank is 24" deep, however, it's ~ 19 inches down to the sandbed.
Also, since I'm building the canopy, and 12" wood is acutally 11", my MHs are only going to be ~ 6-8" above the top of the tank.
Two 250s plus whatever I need for actinics seems like a lot of wattage. With the VHOs actinics that'd be 780w, about 7w / g. Plus I would have to worry about the middle section, so if I put a couple of PCs there it'd be 910 w, or about 8 w/ gallon. That seems a little high to me, as most sites recommend 3-5 w/g.
Since I have a center divider, I can't put one MH
there, and two additional MH
is way above my budget. So I figure my only options are to put my MH
at the ends and some PCs in the middle, or just let the VHOs hopefully take care of it. I can place the light intensive corals near the ends.
So you guys don't think that's too much wattage with the 250s?
