Hello, staying off my fist reef aquarium, I'm sure it's going to be baptism my fire but I love a good challenge and can't wait to learn a lot about the hobby along the way.
Nice tank! I'll try to spare you some of that fire and let you know that at 30" down to your sandbed, those primes are going to be like 12 par. Even halfway where the top of your rockwork ends and they intersect will only be around 100 if they are cranked all the way up.
