I got the raw ingredients for PMDD and made a half 'o liter last week. I have a Red Sea Fe test kit - in fact, just about every test kit anyone would ever want (amm, nitrite, nitrate, phosphorus, iron, ph, kh, gh, etc.).
Ok, so now I have a bottle of my very own PMDD and I have the Sears-Conlin paper about dosing. But there's something on which I'm not quite clear. If your Fe levels are below .1 ppm (or is it 1 pmm, I forget), how can you "ramp" that up without causing major disturbances? Right now I'm dosing according to Sears-Conlin, and adding a couple of extra drops til I get the recommended amount.
20 and 26 gallon tanks, no CO2 (yet).
