Advance 3 part ph’s the water for you.... is the claim , whole ph perfect thing... the whole question I was trying to answer is the cal mag.. what’s in the dispenser water? If it’s 150 ish ppm no need for cal mag..
6.8 is ph.... ppm is parts per million... basically how much stuff is in your water.. water dispenser? So reverse osmosis water ? Def must have cal mag cause RO has nothing in it
There’s def no cal mag... but you only need cal
Mag if your using RO water or distilled... if your using tap check your ppm if there around 150 your good, any lower need some cal mag, any higher than 150 and I’d suggest calling water company and getting analysis of what’s in it
