Higher Calcium Levels & Stable pH

[smallpooldad]

Further follow-up.

Increased Calcium to 425. The strange thing is that although the pool starts of at a pH of 7.5 if it is very, very sunny the pH actually drops if the cover is off to about 7.45. Have no idea why this happening. Later in the day (5 hours later at about 5 pm) it returns to 7.5, sometimes it might get up to 7.52. This only occurs on very sunny days. SWG runs from 11 am to 3 pm.

This is confirmed by my friends pool that also displays the same tendency. The only difference in his pool is that he has no borates and the calcium is 375. His SWG runs from 8:30 am to 4:30 pm.

I do not expect a reply but I thought it might be useful to you to follow-up, maybe not.

Aloha and thank you for all your kind and polite replies.
