i just flushed, cleaned and wax the spa. i filled it with water and got the TA from 220 to 80 and i added the Sodium Bromide 2oz package. i waited about a half hour with jets running and i added 2 tbs of granular chlorine. let it run about 15 minutes and had to close it up becasue of a storm. 3 hours later i have no bromine reading. i had this same problem the 2 other times i filled this tub and did the bromine setup. the last 2 times i added granular chlorine no reading, mps no reading, and then i dumped a cup of liquid chlorine and i can't remember if that worked or if i had to add the 1 setp bromine witch is 14.7% bromide and about 82.5% granular chlorine. witch makes me feel like the 2 oz package of bromide i bought is junk.
this time i added
2 tbs of granular chlorine should of gave me a reading of 20+
then i added the last of my mps witch was a 1/8 cup and it did nothing.
i just dumped 3/4 cup of 8.25% bleach in.
just tested with the k2106 kit and the water doesn't turn pink so no bromine.
what am i doing wrong? why do i have to dump so much stuff in and i still don't get a bromine reading?
can the Sodium Bromide go bad?
