Greetings,
I'm having a problem getting my hot tub water chemistry to balance. I've spoken to my dealer and read the TFP guidance, and I've been diligent with my record keeping.
I hope someone can pinpoint what I'm doing wrong. The short version is that I cannot get my pH to come down from > 8.2 into the ideal range.
The long version is detailed in the table below with notes about what I see going on and what I'm attempting to do each time.
I'm only measuring pH when Alkalinity is between 80-120. I understand that "Spa Down" lowers pH at a greater rate than Alkalinity, but I don't understand why I'm never getting into the ideal pH range before the Alkalinity drops out of range. Especially since the Taylor Acid Demand test seems to come in at reasonable number of drops. I'm adding the correlating amount of acid to get the pH to respond with no movement.
I've used test strips to compare my Alk and pH readings, so I think my test kit is fine. None of my Taylor chemicals have expired.
Any suggestions?
Thank you in advance.
