I have been keeping reef aquariums for a few years now. I started off with 250 watt MH for my first tank. Switched to Radion Pros for my current tank (75 gal).

I have not been able to dial these things in yet. Currently the fixtures are 6 inches off of the water mounted in a canopy. I have tried increasing the intensity over 35% and it killed half my coral and fish (ich breakout).

I am running a chiller and keep the tank at 80 degrees, have big skimmer, uv sterilizer, and monitor my levels like crazy. Yet, I my corals suck compared to my MH. Fish seemed stressed. Overall not working out well.

Attached is my current lighting cycle. I am using Ecosmart Live, radiant color template, on for 11 hours, with peak intensity at 35%. Am I running these things wrong?

Thanks for the help.
