Im still kind of confused here, if my tank has no algea present in it, but my po4 test at 0.03(hanna), and no3=2.5, which they are pretty low, but some of my corals are still ugly brown. Should i try dosing vodka in small amounts to try to get the no3 to 0 and bring down the po4 some. Im just tryin to find a good way to lower it and also get some good color back. I always thought i was nutrient lacking because of the no algea in the tank, but there must be something going on because of brown corals. Any ideas should i try the vodka, thanks
