Aeration and its effect on pH

[KurtV]

JB,
You can raise pH through aeration but that's normally only done in an attempt to lower TA (you first lower the pH which also lowers TA and then aerate to allow pH to rise without rasing TA).

Most people raise pH by adding borax (regular 20 mule team borax from the grocery store).

Why do you want to raise your pH? It's in the acceptable range of 7.2-7.8.
