Hey guys a little background, my tank is about 2 years old. I had a crash and most livestock died. I left it alone except for topping off evaporated water. It’s a standard size 90 gallon tank. Anyway, I’ve left my lights at 100% corrallab LPS settings. As you can imagine, I got a bunch of cyano from bad water and dead stuff. I’ve replaced all the bad equipment and have good water. I test daily for Ca, Alk, and magnesium. I test 2-3 times a week for phosphates and nitrates which are usually zero except for recently I’m up to 2 nitrates from me feeding my new fish and corals probably too much. I do frequent 20% water changes and reduced feeding a lot but the cyano remains. Is anyone else running 100% LPS in a 24 inch deep tank? It’s 48 inches long and I have two radion xr15 gen 4 pros with diffusers. Am I way over doing the intensity? Corals seem super happy
