What is Black Treat?
Black Treat is an E.P.A. registered algicide 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.
