Yikes, your post showed up to me after I wrote my last one. Sounds like Baquacil is expensive and maintenance intensive. I use chlorine, acid, CYA and salt. That's it. I'd be surprised if I spend more than $100 a year. And with my SWG and acid injector, I spend about 5 minutes a week on my pool (pretty much just testing to make sure my gizmos are working). That's it.
