How do you get rid of black algea in fish tanks?
To get rid of black algae, soak the tank in hydrogen peroxide then rinse it off after some time. Reduce the amount of light in the tank since this contributes to their growth. Find more information at http://www.aquaticcommunity.com/algae-control/black.php.
