Hi out there, it's been a while and I don't do this online stuff often but have no one that I know with knowledge of reef tanks. I would appreciate anyone who has coral letting me know the percentage settings to set the lights at. I don't understand spectrums. After a severe algae bloom a while ago I'm still getting the tank together but have a Black Dot Damsel fish that is way too big to add any fish to the tank and until I manage this lighting all but one coral has died and he's not far. It's amazing I went 15 years with a thriving 180-gallon tank with no real problems and because of the first of several algae blooms all is gone. My water is within all parameters and I run a refugium too about 40 gallons. Apologize for the speech but I don't know any other way....Kevin
