How do I get rid of black algie? The stuff keeps coming back and we have treated and treated the pool.
Thanks for a reply.


Black algae can be very stubborn. The most important thing is to do is make sure it is completely gone. Scrub the affected area to get to the core of the algae and allow the chlorine/algaecide to penetrate. You may also want to adjust the circulation to direct more flow to the most common affected areas. Also make sure the algae is not starting in a dead zone where no water is being circulated.
