Changed water and replaced filters. Water is at perfect balance per test strips and is crystal clear with very little to no foaming even when jets are on... but there is a sticky blue film around the entire water line that is very difficult to clean. It gunks up the cleaning pads I use to the point where it just smears before I've cleaned a quarter of the spa. I am using the following... Clorox Pool&Spa 33506CLX Pool Shock XtraBlue Clorox Pool&Spa 12104CLX pH Up 1" Inch Pool/Spa Chlorine Tablets Spa/hot tub/Pool Chlorine Floating Tablet Dispenser I've been using this method and chemicals for quite a while without this problem previously. Any thoughts?
