I currently have 1 Fluval Marine 3.0 on my 90 gallon. It was on my 70 gallon, but I'm concerned about par and the depth on the 90 gallon. I was thinking of adding another Fluval Marine, but will that do anything for par for depth? I'm looking at growing mainly lps, maybe a birds nest. But I don't want to put all my corals mid to high in my tank. I'm considering 1 Radion xr15 blue for right now for over the middle to supplement and then maybe another xr15 blue and moving them to the side and getting rid of the Fluval. Also looking at Hyrdra 15 but am not to crazy about it's height requirement for spread. Adding a second Fluval is the cheapest option right now.
