My dKH is 7.0 and Calcium is 400. After 6 months, I think it's time to start dosing. I am going with 2-part - mainly due to space. I am also a DIY and would like to use Randy's formulas. I have used the calculators provided by Randy - but it leaves me confused about the amounts. Are the amounts what I should mix into 1 gallon of RODI? If so, how much do I dose in mL per day?
Stated another way; how much do I use for mixing a batch vs how much I dose per day to maintain targets?
