Pool Mate 1-Quart 2-Pack Concentrated Black Algaecide - Kills Black

In this review the Pool Mate 1-Quart 2-Pack Concentrated Black Algaecide is presented as a straightforward solution for pool owners battling stubborn algae. It is aimed at people who need a weekly maintenance product and a concentrated treatment that can both prevent and kill black algae without closing the pool. The single biggest reason to buy is its concentrated, non-foaming formula that treats visible algae and provides an easy weekly maintenance dose, making it useful for routine pool care and algae control.

Key Features

• Controls black algae: Specifically formulated to target and kill black algae so owners can clear affected areas without a full pool shutdown.
• Concentrated formula: A little goes a long way, with measured doses for visible algae, initial shock and weekly maintenance to keep pools clear.
• Non-foaming and non-metallic: The product is designed to avoid foam formation and metallic staining that can affect pool surfaces.
• Works with all pool types: Safe for vinyl, fiberglass, concrete, gunite and other common pool surfaces when used as directed.
• Simple application: Dilute with at least nine parts water and sprinkle around the edge while maintaining circulation for even distribution.

Who It's For

This concentrated algaecide is best for residential pool owners and maintenance professionals who need a reliable weekly preventative and targeted treatment for visible black algae. It suits pools of all common construction types and those who prefer a non-metallic, non-foaming chemical to avoid staining and surface damage.

Those who should look elsewhere include pool owners dealing with extremely heavy algae blooms who are unwilling to perform mechanical cleaning first; heavy infestations require cleaning before treatment. Also, if a user has experienced foaming with other products, they should monitor their pool closely on first use since some users report foaming under certain conditions.
