How do you determine total ppm from the feeding schedle you posted to be sure that you are using the proper CO2 levels. You poste the schedule in mL added, right LoL? Could you post a CO2 schedule as well or explain how to calculate CO2 levels from the feeding schedule that you posted. Different EC meters seem to have different formulas for calculating ppm levels and converting to EC readings. Hope I wasnt too confusing. I am doing lots of research concerning this thread. It woke me up to what is possible with using a little inginuity.

Thanks Again for your generosity.
