Problem: Bromine level is too low.
Got a new (my first) hot tub - CSXi80 (Costco/Evolution/Strong). ~1300L hot tub. Read a bunch of the threads here and decided on the 3 part Bromine system:
after adding balancing chemicals, baking soda, etc
pH is good
Alk is a somewhat high
Calcium fine
Added small packet Bromine Booster (Capo industries), presumably this is Bromide to establish bank/reserve
Used liquid bleach (perhaps now a total of 2 cups over 2 days - 1 + 1) but can't seem to get Bromine level up and it's been 4 days now. I've also got Bromine tabs in a floater.
My spa has an ozonator (btw, how can I tell if it is actually working?!).
I've been using test strips (sorry don't have the brand at hand at the moment). Is it possible the test strips are erroneously showing low bromine levels? I don't yet own a good test kit and wasn't sure if that was necessary, especially when one can just go a pool/spa shop to have one's water tested.
I don't know what I should do? Add more of both the Bromine Booster and bleach, or just bleach, etc. I guess I should probably go and get my water tested but then I don't want them pushing stuff on me to buy that I don't actually need.
Hoping someone can offer this newbie some advice.
Thanks.
