Big ph drop?

[Farmerstan91]

First year with the pool and initial fill had hard water in it ta-140ish if i remember correctly and had to drop ph every 2-3 days at first then spaced out as my ta came down. Pool finally leveled out at 7.6 2-3 weeks ago and has stayed steady since. Last checked it sunday at 7.6 then checked this morning and its down to 7.0 and ta is at 60. Anything happening i should check or just raise the ph and move on with life?

pH can only drop if you add acid (or acid containing products) to the water.

How do you chlorinate?

How about posting a complete set of test results or sharing PoolMath logs?

Fc 2.0
Cc 0
Ta 60
Ph 7.0
Didnt take the time to check ch or cya

Check the pH again.

What was the last TA reading before the current 60?

FC of 2.0 is likely not good but can't judge without CYA.

I agree with everything mknauss posted above.
Too, if ever test results reveal a drastic change, I re-test, 2/3 times and double check if Reagents expired?
Im guessing you would already know if the proximity of your fields and power machines to your pool could be a factor And whether or not You switched chlorine dose or type...

Ran back home and checked again and got 7.6 like normal. Typically i check late afternoon early evening with the pool running. Today was barely day break with pool off. Thanks for the help everyone
