Ordered 3 ai hydra 26 to go over a 150 DT. The are mounted 10 inches above the water, and are upgrades from ai sol blues. I have the lights set at 20w, 30 blue and royal blue. Everything else is off. Thought I would try and mimic my old tank settings except for intensities and slowly work up. Problem is all my corals are browning or rtn ing. All parameters are spot on. Any insight would be greatly appreciated. Thank you in advance.
