I've had my swim spa (1500 gallon)for about 4 weeks now and realized about a week into it not to trust the advice I received at my spa dealer!
They were asking me to shock my pool each week with Dichlor, and now my CYA level is between 50-60. I do seem to need a lot of dichlor on a regular basis. (we swim in the spa almost daily).
Considering adding bleach when needed (and giving the pool guy at Leslie's a coronary) vs. switching to bromine tablets. Pool guy from Leslie's suggested Cal Hypo instead but my Ca level is perfect right now and I don't want to mess with it.
I read the bromine sticky and purchased some bromine tabs as well as bromide powder to create a bromide reserve. Questions:
1. Should I switch or not? I'm a little concerned since I travel and may not be able to check the pool for up to a week.
2. I notice the bromine tabs for the float have additional chlorine in them, I presume to oxidize the bromide to hypobromous acid. See below. Is the 1,3 dichlor-5,5-dimethylhydantoin that is mixed with the bromide the same as the "Dichlor" in my shock. Will it raise my CYA levels? Does it matter? Answered...
3. What level of free chlorine should I start this process? Wait until it's low? Does it matter?
Thanks,
Chuck
Edited to add: I figured out the DMH is the stabilizer with bromine and is analogous to CYA, so I answered that question.
