Subsonic Pools always seem to me as if the juice is not worth the squeeze. It is like having a never ending chemistry experiment in your backyard.
This became somewhat true for us after all the kids moved out. While the kids were living at home, the pool enabled us to know where our kids were and who they were with, because they were mostly in our backyard. Priceless.
Re: the chemistry. Once you have it figured out, it's minimal maintenance. You just have to be on a routine.
