my 90 gallon reef

[dione]

Hi everybody, I am new to this hobbie like to get some advice. I just recently purchased the AI solid blue system and have a little bit of concern for my corals cause are getting bleached and they look like they are dying. I was running the system around 70% for the first week. then reconized the curls were getting bleached. Now i have been running the system at 30% to 40% for the past 2 weeks my water level is normal except for my calcium it is a little bit high and my magnesium is also a little bit high. Can someone out there give me some good advice that has the same system and to properly adjust my lighting.

Not really a large tank. You will get more help in the lighting forum. I think you had your AI's set to high, 70% is what many run theirs on after acclimating. It will take time for the corals to recover from bleaching.
