nice, Sarah. Right now, they are at the 7 inches --highest the brackets go. I have them spaced about equal across an 18" wide tank and full length. Will adjust lights to more green and red.
thanks @mcarroll Prob. should put them at least down to 5". No real corals in there yet, just a few extra frags. With 2 lights, 18" tank, 22 deep, should I go 3 now or wait for corals?
You mean three inches, right? You may as well get it into position now so you can see how you like it overall.
