Can Letting Chlorine Get Too Low Raise pH?

[Michael1]

I noticed a strange phenomenon. If I neglect my chlorine level, and it gets too low, to the point of creating some algae, I have found that the pH goes sky high. Is there an inverse relationship between chlorine level and pH, perhaps indirectly through some other mechanism?

I can't think of any connection whatsoever.

I think your pH rise is also a matter of neglect.

pH's rise by the following
* a lot of aeration
* excessive rain [both dilution and aeration]
* the addition of baking soda or other alkaline based products
* not adding any muratic acid or similar...

So, which ones are happening to your pool?

I can't think of any reason in particular the pH goes up so much, no rain, no alkaline products, no aeration. This pool eats acid at the rate of about a quart a week. Seems worse as we approach summer. Is that normal?

I use more than 1qt per week in my pool.
