Good Day, All!
I'm looking to raise the GH of my RO/DI water product. According to the Barr formula: 3 parts potassium sulfate, 3 parts calcium sulfate, and 1 part Epsom Salt in a bag.
My question is what is meant by parts? Is it based on the molecular weight of each? So would I essentially have to add 361 grams of K2SO4, 361 grams of CaSO4 and 246.47 grams of Epsom?
Ex: Molar Mass K2SO4 = 174.26, CaSO4 = 136.14, Epsom = 246.47 (essentially, 120.37 MgSO4)
Do I generally measure 300 grams of K2SO4, 300 grams of CaSO4, and 100 grams of Epsom?
Thanks for your help!
