What is Black Treat?
Black Treat is an E.P.A. registered algaecide formulated for the killing and elimination of black algae in chlorine/bromine pools.

How do I tell when I have black algae?
Black algae grows on the walls and floor as a black spot that you can scrape off with your fingernail. It is a colony algae that is very hard to kill. You must run a continuous preventative program after you have removed the visible colonies. If none will brush off, look out, you probably have cobalt staining. Use United's Cobalt Cure for cobalt. Cobalt happens only on fiberglass or epoxy.
