How brown did they get with the po4 that high, i hate it when my po4 hits around 0.05 so im sure you were mad. How long do you think it takes to color back up when the po4 is dropped back down to 0-0.04. Im just curious i have a couple corals that just wont color back up since my po4 was out of control. I now keep it at 0.03 most corals look great but theres still a couple. I also have some that are dull looking now and im wondering if thats from lack of nutrients now. Anyways glad to see you getting it under control mark.
