i have the taylor test kit. when doing the OTO test. i get a dark yellow reading suggesting 10 or higher.
Can one use the regular 10cc chlorine test on bromine or am i wasting my time. i have tested it this way a couple of times to see how much combined bromine/organic matter i have.
i seem to always get a reading of 2.5-3 even after i shock it. i am beginning to think that this test does not work with bromine.
how can i check my combined bromine in a spa, or do i not need to do this just shock on a weekly basis?
