Jacks Magic Solution 2

Is this true?
No.
At the time you add it, the liquid chlorine will slightly raise the pool water pH. Slightly. But as the FC is consumed by UV and organics, it is acidic which neutralizes the slight increase. So overall liquid chlorine is pH neutral.

Elevated TA is what causes pH rise.
 
I spoke to JAcks Magic today who told me that bleach raises ph by 13. Is this true?

Not exactly.

Bleach is pH neutral.

It is a myth that liquid chlorine will raise pH. The myth is based on a misunderstanding of chlorine chemistry.

Adding liquid chlorine to water can cause a temporary increase in pH, usually offset by the chlorine reacting with organics and biological matter, which are acidic (creates a proton) reactions. Thus, on balance, the net chlorine reactions are pH neutral.[8]

Most retail and commercial liquid chlorine products contain a slight lye excess from the manufacturing process. Still, this amount of OH- is minimal and does not change the pH with normal levels of liquid chlorine use.

If one were to add significant amounts of liquid chlorine (for example, raising the pool water chlorine concentration to SLAM FC levels), the pH rise would need to be offset by lowering the pH with acid. This is why TFP requires a pool owner to adjust their pH down to 7.2 before starting the SLAM Process.

Adding liquid chlorine DOES increase the pH at first; however, as it's used up, the acid that's created lowers it back down to where it was before......thus equaling each other out, making it pH neutral.

My ph is constantly high and this would explain why, although I always thought that adding bleach to my pool did not effect any other chemical in my pool.
What is your TA?

Thank you. My Ta is at 50 so I wonder why my ph is constantly in the red.
