Hello all,
I am just getting my spa running and i have hit a snag with the water chemistry. I checked the PH, CH, and TA of the water. My CH reading was 100ppm so i added 6 TBSP of Calcium Chloride to raise the CH 50ppm to reach 150ppm. Then I added Sodium Bromide to establish a bromine bank. I added approx. 1.7 oz of Sodium bromide to establish a bromine concentration of 30 ppm as per the directions on the bottle(0.5 oz/100gallons). When I tested for bromine, about 1hr later. I got a reading of 1.25ppm. 7hrs later the water did not test positive for bromine at all. Is this normal? I am not sure if i should shock the spa then do the bromine test or do i need to add more Sodium bromide and get a reading of 30ppm before adding the shock.
I am using a talyor K-2106 test kit
330 gallon spa with ozonator
thanks in advance
