City tap water - pH 7.7, TA 50ppm, CH 50 ppm.
After balancing - pH 7.5. TA 60ppm, CH 160ppm.
I removed several pails of water and relaced with tap water to lower the CH below 150 ppm.
Added Gentle Spa (4 oz per 150 gal) to get 40 ppm.
Added (125ml per 1000L) sodium bromide to get 30 ppm.
During the 3-4 days of water balancing I maintained around 3 ppm FC by adding 1-2 oz 10% sodium hypochlorite daily.
Today my pH is over 8 and my TA is 100ppm.
If the TA was 60 ppm and I added 40 ppm Gentle Spa should the TA be 100ppm?
What did I do wrong?
