Hey everyone new to the forum, I am posting because for as long as I have owned my spa Ive always had a issue with very high PH and alkalinity on fresh refills. This time seems to be different, I can not bring the PH down and the alkalinity is low. When I first tested after filling it up a day later after the spa has warmed up the PH was 8.2+ and alkalinity was 420.
Added about 2 cups of acid and about 3lbs of PH down and PH is still around 8.0 and alkalinity is at 80. Every time I add 2oz of PH down it will go down and a hour later it will be back at 8.0 and has been like this for a week now. I have been adding alkalinity up to try to keep it in the normal range and I'm sure that is bringing my PH up a bit but this seems a bit extreme this time.
I have brought the water into 2 different places to have tested by computer and so far nothing has been close and they keep saying to add more PH down and alkalinity up to bring it into spec, been following what they tell me to a T but nothing seems to be helping.
