PMDD -- Is my list complete?
I am new to the whole PMDD thing and want to make sure I have collected the right ingredients here.
1)MgSO4 (epsom salts)
3)KNO3 (Grant's Stump Remover)
4)Mono (and di-)basic sodium phosphate (Fleet Emema)
So, from the reading I've been doing, it seems that all I have left to worry about is an Fe and C source. I will be injecting CO2 (pressurized cylinder) and will aim for 20ppm. Fe (and traces) will come from Plantex CSM + B. Am I ok here, or should I add additional Fe? I've noticed the "Extra Iron" CSM+B and was wondering if that is any good.
On a slightly different, but still related note, I live in an area where the tap water is EXTREMELY hard and alkaline, so I will be using R/O water, which is very soft and pH=7. Will adding PMDD create a buffering capacity for the water, so the pH swings less(or none) from the injected CO2, or should I be adding something to increase the KH? Thanks.
