Dear water chemists,
I am running into a strange issue. My RO water which i'm slightly blending with the raw water (after carbon and sediment filter) shows a pH of 7.1-7.2 which is what I want. Now when I heat it up the pH seems to be shooting up to 7.9-8.0. I thought it was a problem with my HLT and so I took a small sample and heated on the stove to check. Got similar results.
Ca 10
mg 4.1
Cl 26
SO4 1.8
HCO3 68
Na - unknown
Alkalinity 56.2
total hardness 42.4
What could possibly going wrong and how can I fix this?
When I stop blending the water pH is too low 6.5
