Cedar hot tub

[Revid]

I have a cedar hot tub and bought a Aquachek meter to read levels. Iam using bromine cause I read it was better for the cedar wood. The meter has CL, PH and ALK on the screen for readings. What are my bromine levels supposed to be and under what space should it be CL or ALK? The paper said it supposed to read bromine and booklet says to multiply free chlorine by 2.2

Your meter does Chlorine, Alkalinity and PH.

Bromine is read under the CL reading which is why it says to take the free chlorine reading and multiply by 2.2. Bromine does need to be in a higher concentration.
