Welcome to our forum.
I have an additional question on this subject- My husband and I will have to be away from our hot tub for a minimum of 3 weeks at a time, and would like to reduce the amount of maintenance we have to do each time we come back. We were thinking about a service, but one of the local spa dealerships suggested that we remove our bromine filter and just use a silver cartridge and ozonator. I understand what was said in the previous post, but is this combo effective for a long period of coverage without any additional treatments?
