I am not sure if this is possible or not, but here goes my question.
I currently have an in ground pool with sag.
In my new spa, I am using a 2 part bromine system, combined with a swg? The swg helps in keeping the bromine constant while we are not adding spa pucks after use.
I find this spa is easily twice as much work as my pool and want to convert it over to chlorine.
Can I use the water already in my pool, which cya levels of 60, and put it in my spa? I would then simply add bleach after each use.
Secondary question would be, can I then retrun that water back into the pool when I wanted to change the water out?
Any help would be appreciated as BBB has me running my pool on less then $100 a year.
