I have a Jacuzzi spa that uses bromine. It isn't attached to a pool and is covered when not in use.
I can't seem to get both pH and TA to the correct level, assuming that the TA should be around 100 for my spa.
For example, I will start with a pH of 7.6 and TA of 40. I add the chemical to increase the TA. It will cause TA to go up to 80 but it will cause the pH to go up to 8.0. So I will add MA to reduce the pH which will go down to 7.4 but the TA will go down to about 30. So I will add the TA+ and cycle through this again.
Anyone have any advice?
