d.sebens Posted March 31, 2021 Report Share Posted March 31, 2021 I haven’t paid attention to how much I use to raise bromine. I use regular bleach. Does the table for raising chlorine translate into bromine level when adding chlorine? I should be measuring but I just dump some in and test them dump more in till I get there. It would be nice to have an idea how much to add to bump it up. Quote Link to comment Share on other sites More sharing options...
d.sebens Posted March 31, 2021 Author Report Share Posted March 31, 2021 Also, @waterbear you mention that when using bromine to kind of embrace higher ph and not fight it. My results are TA 60 PH 8.0 CH 200 With borates. Should I target a lower ta and aim for 7.6? 7.8? Should I just let it be? Quote Link to comment Share on other sites More sharing options...

That makes it easy to know how much to put in. Quote Link to comment Share on other sites More sharing options...

Do you have an established bromide bank in the water? Quote Link to comment Share on other sites More sharing options...

Maintain a pH of around 7.7 to 7.8, when it hits 8.0 lower it back to 7.7 or 7.8. Drop it to 7.6 if it's easier but realize that it will settle around 7.7 and the slowly start to climb. We want to maximize how long it takes to climb back to 8.0. Borate, not lowering pH below 7.6, and keeping TA low (50 to 70 ppm) are how e achieve this.

Yes but have lost some water due to over flowing and a hose coming off. Have just cowboy’d a little more sodium bromide to it. 25 minutes ago, waterbear said: Maintain a pH of around 7.7 to 7.8, when it hits 8.0 lower it back to 7.7 or 7.8.

I have to be getting close to where it will balance for a while. Do you recommended borate strips or can i just guess. I put in the right amount when I filled the tub but have lost probably 1/3 to 1/2 since filling. I added enough borates for 1/3 cap of the tub. I was using the gentlespa stuff.

MUCH easier to read that Taylor, Hach, and AquaChek. LaMotte have a change from rose pink to tan, the others are very close shades of tan.
