Agreed, some phosphates is good. But i have to run gfo to keep them below .1ppm.
And normally I'd leave it alone, but i'm trying to get nitrate off the floor. As i raise nitrate by feeding fish and corals phosphate is rising way faster.
My ideal range would be 1-2ppm nitrate and .05ish phosphate. I know I can't control that, but i'd like to get it close and balanced.
Yup skimmer is fixed and pulling some thick stinky crap out again.
