Too much (above 1400) and too little (below 1200) can be problematic.
I would check this parameter.
Also nitrates and phosphates at zero are not good for corals, they need an uptake of both....nitrate 2-4 ppm, max of 5ppm, phosphate at .03-.05

I will test mag once I get home. I know that nitrates have to be higher, I will be feeding 2x a day now. I think I have phosphates actually because of the bubble algae that I’ve seen I just think my phosphate test is picking it up.
