Quick Question About pH DROPPING???

[Watermom]

Have you had a lot of rain? Whenever I do, I sometimes see a drop in ph.

I think it is still left over from your stain treatment. What is your alkalinity? Post your numbers if you can. The stain treatment is very acidic, and can be effecting your ph. You may want to keep your ph at 7.2 for now - it will help your chlorine to be stronger, plus it will help keep any metals that are in your water from dropping out and landing on the surface of the pool again. Your chlorine is still fighting something that's why it's getting eaten up. Keep an eye on your ph, and try to keep it at 7.2 to 7.4. Your ph will stabalize once the chlorine is finished cleaning up and filtering out what shouldn't be in the pool. Check your alkalinity, because you can also get into ph bounce - all of the chemicals work together, that's why it's great once the pool is balanced - and don't worry you will get there!!!

Watermom,
Unfortuantely, NO -- it's been EXTREMELY DRY here.
We had a brief thunderstorm today that gave us a pretty good soaking, but that's the first one in about 2 weeks.

Marie,
THANK YOU! That's what I wanted to know & needed to hear... I will stop worrying now.
My current pool readings are:
Temp: 78 degrees (must have been a cold rain!)
FC: ~10 ppm
TC: ~8-9 ppm
pH: 7.2
Do I need to check TA & CYA again? They were both fine 2 days ago...
I will if I need to!
I have a regular chemistry lab set up on my dining room table.
Thanks again for the help,

I would check them to see if they changed at all. It is good to see what your cya is because it will change how much chlorine you need to get into shock. You want to check your alkalinity because the stain treatment can mess that up too. You are certainly on the right path - your pool looks beautiful, once all the algae is gone and you can get your water in balance, it will be a cinch to keep it that way.
