Hi TFP'ers,
This is applicable here b/c mostly it pertains to water chem, not just spas. As such, that is why posting here.
I have bromine spa. Changed out water on Sat. following this site, as I usually do:
How do I use Bromine in my spa (or pool)?
and I also use this site for reference too:
How do I use Chlorine in my Spa (or pool)?
?s
1. I float bromine tabs. As such pH typically drops. This water change, decided to try to keep higher TA to see if that will slow the drop. Old water TA was ~80. This water I decided to start water at TA 120 to just see if that will help. Overshot when added 2 oz 2 tsp baking soda and water at TA 130, which is fine. pH was 7.2 so added 1 oz borax. Then I added 2 oz chlorine to shock/activate bromide bank. When rechecked, pH 8, Br 8, and TA 130. Should I start chasing the pH? Please refresh my memory as I thought the pH rise from my 7.6 just d/t having added and shocked with the chlorine, right?
2. I already planned to start with the TA at 120 or 130 and see what happens over the next few days/weeks if the pH will still drops as it did on old water. Objective is simply to see if keeping higher TA will slow the naturally tendency for it to drop from the bromine tabs. Sound plan?
Tx in advance.
