Newbie to this form but not to pools, water maintenance, etc.Have been going to a (nameless for now) well-known Pool Store nearby for help about setting up my spa water chemistry.
They are USELESS at solving spa problems. Testing of my water at a different temperature from what I experienced and what I read on these pages is TOTALLY DIFFERENT from water balance tests in ambient temperature both as to Chlorine, pH, and TA. As a result of their skewed (being kind) advice, I have been having serious acid/akalinity bounce, ±2.0.
Now I have questions here:
1. Is it better to start over (e.g., dump the water) to get the chemistry right??
2. If otherwise, and I can get a handle on water history quickly, I'd like to corral the water settings. Can I do it given the fluctuations? My Bromine level (Br) is now off the chart ~12.0(?), and my pH= 7.8. Acid Demand = ~80. Water temp (measured on the SpaCrest sensor)=99°F. SpaCrest (recommended) runtime 7 days, 7-11A, 11P-3A).
3. Is run time correct?
