I have to confess I'm a little curious about this product myself. Also a little fearful. When I read "polymers" as a product component I think of multi-viscosity motor oil, where polymers string together to allow 5w motor oil to cling like 30w. Then I imagine this gooey stuff clogging my filter cartridges and accumulating here and there where it reduces the rate of water flow. OTOH, I also wouldn't mind removing "scrub waterline tiles with brush and muriatic acid" from my ever growing list of periodic duties that increasingly make being retired seem less like being retired. Anyone have extensive use of this product with filters--as well as other things--being unaffected? And how long it lasts?
BTW, my CSI calculates to 0.07 most recently, but I still get calcium deposits on the tiles above the water line. Not a lot, but what I get is really stubborn.
