Well I took the skimmer offline today. I believe it was implemented to early or is way to big for my tank. Most likely both. My nitrates are 0 when I'm not dosing. I dosed them slowly back to 5 and will monitor it carefully until I get ahold of it.
I believe nitrates and phosphates being low is why I'm not able to keep corals atm.
I think the skimmer was pulling to much out is my theory.
I did buy this skimmer knowing it was to big. But I took the chance with hopes of using it on a bigger tank in the future.
I honestly have zero interest in upgrading this tank until I can get it rocking for a few years.
