8 feet of crystal clear water. Having issues with the tank and I think I know what it might be. When I was transferring the lights I dropped a washer and couldn’t find it. I may have to pull the rocks out and go fishing with a magnet.
Nope. Took out 10 gallons of cheatomorpha out of my sump so I’ll look there next. I also have live rock for the new tank down there. I did get some couprisorb to see if it’ll pull anything.
My other thought is that maybe my lights are turned up too high for a ULNS. I turned down my kessils to 25% and my reefbrites to 10%
Yeah I checked Kessil AP9X with a par meter. At 8" deep set at 35% there were spots were I was getting 350+. Down about 15" deep I was still getting 200-250 and 20" deep on the sand bed around 120-150. The Kessil lights really penetrate the water well.
