    You're on the right path!

    It's always a pleasure to help someone who is willing to listen to the advice and do the work involved!

    Though there is probably a better place for this; I want to mention the SWCG= rising pH issue. As a result of salt being electrolytically converted to chlorine, a couple of hydrogen atoms are left over. They form a bubble of hydrogen gas which is introduced into the pool via the returns. This causes aeration, which raises pH. The concentration of hydrogen bubbles, per return effects the aeration process (the pools I built in Ct. had ~ 12 returns !?! (7 regular returns, 2 in the steps and 3 low returns)) Because we split the excess hydrogen between 12 returns, I never saw the pH creep often reported- but I certainly did on pools that had 2 - 4 returns. I hypothesize that the hydrogen is more aggressively aerating the water in pools with fewer returns thus causing the constant pH rise

    Having done construction and service for 4 pool companies in 4 states starting in 1988, what I know about pools could fill a couple of books - what I don't know could fill libraries

    Thanks Ted. My pool is an AG so I only have one return which could be even higher PH rise. Once I try the acid a little at a time I will look for a drop. If it does I will just have to keep it in check and if it rises with the SWCG I will bring it down again. My only question is I keep reading when I put in the Muratic Acid I have to aerate but with an AG pool how do I acheive this?

    Aerate by pointing the return jet upwards to create as much turbulence at the water surface as you can. A pool full of splashing kids will also aerate.

    Hi Mr Mooks,

    I'm in Pickering ... looking forward to 38C tomorrow.
