Anyone ever heard of (or utilized) Jack's Magic Blue Stuff ?? It claims it "removes" metals from water EVEN AT high CL levels ?

Developed a metals issue a few years back and have fought it ever since.... Any "shocking" procedures drops the metals out of suspension and I wind up with staining....

When I saw the Jack's Magic, I assumed i could shock without the staining...? Any ideas ??

(Hoping everyone's been well)...
