Attached are images of what I am dealing with, although I still cant seem to get a firm ID on what this is so I am scared to take any incorrect action.
I have cut my white lights to 0% and blues at 50%. As of today my nitrates are at 5ppm and my Phos at .02ppm. Should I risk carbon dosing as my parameters already seem low and I dont want to bottom out?
About a week ago I gave my corals reefroids which popped my phos to .06 and caused my corals to slime, so I did a water change which dropped my nitrates to 0, Phos stayed at .03. I noticed within 12 hours my nitrates were low and cut my skimmer off which brought me back up to detectable levels of around 7ppm after 24 hours.
It may be worth noting that I have not seen any growth of this particular algae on my rocks and it seems limited to the sand for now...
