everything is going great, growth, PE and coloration is very good. I am very pleased with how things are going. I plan to take some more pictures of my corals this week end to show how its going. Technically, you should be good with 2 on a 90. I have 4 on a 180. 72x24x24.
Yeah I was thinking maybe adding a third even but with having that center brace on my 90g it will make mounting that third light challenging for sure.
