I've gotten used to the BBB system for the pool and it's just a habit now to test daily and pour in the bleach as needed. I'm still learning the ins and outs of using bromine for the spa.
At first it was working fine to keep the dispenser in the spa all the time. Now my bromine levels shoot up when I leave it in. It just isn't systematic and measurable like pouring in the chlorine! Very frustrating!
Does anyone have any helpful experience to share? The spa is kept covered when not in use. Now I am trying leaving the dispenser in overnight and taking it out in the morning. It's on the lowest setting.
