The Purple Stuff is the stain preventative of choice, and a must product for salt (chlorine) generator pools. Unlike traditional sequestering agents, The Purple Stuff works extremely well in high salt and high TDS pools. The Purple Stuff keeps silica in solution while greatly reducing the incidence of cell fouling (scaling) in salt (chlorine) generators.
