Hello, I recently installed an ATI 6 bulb over the 75. I have 2 fish and around 20 LPS corals. So after the 50 hrs burn in time. I mover the fixture closer to the water surface.( I had to hang it very high & add a couple of window screens as the par was way too strong. It was double what the corals were used to. So at this time, I have channel 1 whach has 2 bulbs set at 100% they come open at 10 am & off at 10 pm. Channel 2 which has the other 4 bulbs. Is set At 70% they come on at 1pm and off at 8 pm. The par at the bottom is around 115 to 122. This is around 15 or 20 greater than the corals were used to. They didn't look very good.All corals appear to be perking up ! My question is, does this sound like a reasonable "lights on" schedule? Maybe a longer ? Thanks

It's as good a place to start as any. You can slowly increase the amount of light as long as you don't have any algae issues, or decrease light if you do.
