It was suggested to me to up my PO4 from 1 ppm to 2 or 3 ppm. All that did was increase the issue. I read an article by Tom Barr who was talking about a balance of PO4 and CO2. The higher CO2 concentrations needed less PO4. blah...blah...blah.
Well, increasing the PO4 is usually recommended for GSA, not GDA.

I'm in the "c" camp btw.
