I have used chlorine successfully for the past 12 years on my outdoor pool. Last year I had a low level enclosure installed to extend the season here in the uk. It is now an indoor pool It seems to me that I don't need to use stabilised chlorine as the pool is now very rarely open to the efects of solar radiation. Problem is that chlorine tablets all contain CYA so I thought why not change to bromine? I have to go away for 3 weeks and in the past I would have just loaded up the chlorine dispenser and left t to get on with it. I don't want to increase the CYA in the system as I have recently reduced and that's why I thought about bromine tablets. I know you can't change back without changing the water. What is the consensus? Thanks
