Mysterious pH drop?

[Dan Morrill]

Opened the pool a week and a half ago. pH was 7.6, TA was 140.

The last couple of days my pH had been reading 7.2. No chemical addition yet this year besides liquid chlorine. What gives?

Can leaves and debris affect pH? My neighbor has an annoying maple tree over my pool, it is dropping lots of keys in it right now.....

Only adding acid or acidic items will lower pH.

dropping lots of keys in it right now

What type of keys?

Are they house keys, car keys, or what?

Are you getting any CCs?

Was the sample taken before the water was circulated?

What were all of the numbers before and what are all of the numbers now?

What are the chemistry readings of the fill water and how much fill water was added?

Maple keys, like these:



No fill water or acid added. Is tree debris acidic I guess is the question I am asking?

Test pH in a quart of water, load up with whirlybirds, wait a day and retest. Report your research results to the TFP tribe.

Haha, sounds intriguing. I just figured someone had figured this out already. I'm happy to experiment!

Not enough to account for the pH drop.
