Brightwell Aquatics AA?

I ended with some problems once my tank hit .03 PO4 and 0 Nitrates. Corals started to look terrible and some started to bleach. I think it was just too quick of a change.

I ended up stopping all dosing other than 2 part for the past week and a half or so and things are much better now. Some corals are slower than others to recover but all seem to be getting better.

It was a good lesson. Don't dose anything, especially carbon without testing daily and don't start unless you really need to. I had no real good reason to start.
