Hello, new hot tub owner here. I added enough bromine that I thought I would have a sufficient base. But I test it and it’s showing up as almost nothing. So I add more. And then the next day it is again showing up as almost nothing. But what is odd is when I shock the hot tub than the bromine shoots up way high, but then the next day goes back to almost nothing. Any advice? Thanks in advance.
