I'm still confused about the pps-pro dosage amount and the rotala calculator. Using the calculator in Rotalla it says I need 133grams per 500ml container and 9 ml doses to achieve 4.31ppm. The pps-pro guide that's supposed to be used says 32.6 grams of kno3, which achieves 1.06 ppm using the calculator..
So if Rotala says PPS should be between 5ppm-10ppm, how come the guide says to only achieve 1ppm? Who's right?
