I'm currently struggling with a 0 nutrient system. I had a couple fish. Upgraded to a 120 gallon tank with a 100 sump. Medium Stockton corals. Consistently testing nitrates and phospates and phosphorus ulr with Hanna checkers. Checking phospates and nitrates with salifert. And red sea. All testing zero with the exception of Hanna ulr phosphorus at 3 ppb. I upped my fish load now have 4 tangs and half a dozen other small fish. I feed flake and pellet twice a day rods and reeffrenzie throughout the day. And across just slowly lose color and die. What can I do to raise phospates. My alkalinity is 8.2 ca 410. One other thing is my skimmer is running but I collect no skim it just drops back into tank. Any friendly advice would be highly appreciated!!!!! Oh yeah lights are kessil ap700's two over 4 foot tank a kessil ap700 over my sump/frag tank
