pH of 3.5 - Never before.

Has to be a testing issue. How are you measuring it?

I'll have to check my TA.

I'm testing using a digital meter. I Double checked the calibration twice and it's fine.

I also tested my spa.... fine.... and house water.... fine.... normal readings.

I will say, that I checked the pH this afternoon and it was up to 6.5. So I aded 8 more pounds of soda ash. After 4 hours it now is ok with a reading of 7.6.

I can only assume it was those pucks.... I'll keep the auto feeder turned down more.

Thanks, Tim

It might be best to test against liquid test kit, it seems far too low.
