Ok so it's expelling brown stringy stuff which I'm guessing could be its zooxantelles...which is not good. I have a feeling it might be the light so I turned it down and will slowly bring it up. Otherwise NO3 at 2.5, NO2 0, ph8.2. S.g 1.025. PO4 between 0 and 0.03 (I hate, HATE that Hannah checker).
