I have a Taylor K-2006 test kit. I just filled my hot tub a few days ago, can I test for Bromine like I would chlorine? Use dpd powder and reagents? I realize it would be easier to just use chlorine but I would really like to use up the bromine(sodium dichloro-s-triazinetrione 82.5% sodium bromide 14.7%).
How often do I need to test the water? I use it a few times a week and my wife even less.
