I have been using bromine in my hot tub since we purchased in in 2012, however a friend who stays with us frequently has an allergic reaction whenever she uses it.
Someone suggested that I switch to chlorine and use a sliver ion stick in my filter.
- What does it take to make the switch?
Do I need to drain the tub to make the switch?
How effective is this?
Considerations on my end:
- I changed my water a month ago, and the chemistry is in really good shape at the moment. (other than it makes my friend itch and a little rashy)
I live in the Sierra so its not easy to change water in the dead of winter.
I'm really ignorant on this and am open to any or all suggestions.
