So I've gone and done it.
added about 1.5 tablespoons of sodium bromide and am trying to adjust the bromine level slowly.
I started out with 3.5 FC and then added the sodium bromide. then tested BR and was expecting around 7.5-8 but I got around 2 so I added 20 ml of older( 21 081 date code) 10.8% liquid chlorine and it only went up to 3.3 BR. So I added another 20ML and am waiting a bit before testing again. I hope I haven't over shot. the bromine being X 2.25 makes the target range much smaller but I guess it is supposed to be more stable. I am aiming for 6 BR tonight and testing tomorrow so I can see what my daily loss is.
I read that the CL to BR conversion happens very quickly but maybe the sodium bromide is not active yet.
I understand I just multiply my FC reading by 2.25 to convert to BR. Are the CC readings still valid.
My usual dose is 30ML of the same 10.8% LC daily if no one uses the spa before the conversion to bromine. I'm planning on using bromine with a saltron mini for daily dosing and LC for when it gets used but currently no outlet close to the spa so LC is used for all doses. daily and after use.
