Frequently Asked Questions
What type of algae does Doheny's Super Algaecide treat?
Doheny's Super Algaecide is a broad-spectrum formula that effectively treats green algae, yellow/mustard algae, and black algae. It's designed to both kill active blooms and prevent future outbreaks, making it a powerful solution for all common types of pool algae.
How does Doheny's Super Algaecide differ from regular algaecide?
Doheny's Super Algaecide features a highly concentrated, non-foaming formula designed for fast, effective treatment of even the most stubborn algae—green, yellow, and black. Unlike regular algaecides that focus primarily on prevention, our Super Algaecide delivers powerful results for active blooms while still offering long-lasting protection.
Do I need to shock my pool before adding Super Algaecide?
Yes, for best results when dealing with an existing algae bloom, it is highly recommended to shock your pool first to kill the majority of the algae. After shocking (and once chlorine levels drop to a safe range, typically 24 hours later), add the Super Algaecide to eliminate any remaining algae and provide a preventative barrier.
Can this algaecide cause foaming or staining in my pool?
No—Doheny's Super Algaecide is a non-foaming, non-staining formula that's safe for all pool surfaces when used as directed. It's specifically designed to eliminate algae without causing surface discoloration or unwanted bubbles, making it ideal for both routine maintenance and heavy treatment.
How long does Super Algaecide prevent algae growth?
Doheny's Super Algaecide provides effective algae prevention for up to 90 days when used as directed. Its concentrated, long-lasting formula offers residual protection against green, yellow, and black algae, making it ideal for both initial treatment and ongoing maintenance.
