Re: DI Water Question
It is not alarming to me that it took you 1 teaspoon of Neutral Regulator to bring 5 gallons to 7.0. The dose can differ based upon beginning pH and alkalinity and the existing buffering capacity of the water. This is why the instructions are somewhat vague (1 teaspoon for every 10-20 gallons). For example in water that already relies on phosphates as the main buffering agent, it will generally take less buffer to adjust the pH. However, if water has more carbonates or bicarbonates, then more buffer is needed to overcome those things, so that the phosphates in Neutral Regulator can take over.
