🖤 BLACK ALGAE ISN’T YOUR AVERAGE POOL ALGAE — AND REGULAR ALGAECIDE MAY NOT BE ENOUGH! 🖤
If you’re noticing stubborn black or dark blue-green spots on the walls, floor, steps, or other surfaces of your pool, you may be dealing with black algae. This type of algae can be especially difficult to eliminate because it develops a protective outer layer that helps shield it from normal sanitizer levels.
That’s where Regal Black Algaecide comes in! 💧
What is Regal Black Algaecide?
Regal Black Algaecide is a specialty swimming pool algaecide formulated specifically to help control black algae. Unlike a routine maintenance algaecide, it is designed for those stubborn black algae outbreaks that require a more targeted treatment.
What does it do? 🤔
When used as directed as part of a complete black-algae treatment, it helps attack and control existing black algae and prevent it from continuing to spread throughout the pool.
Why is a specialty treatment needed?
Black algae is notoriously stubborn. Simply shocking the pool or adding your normal weekly algaecide may not completely eliminate it. Its protective coating and tendency to establish itself in porous surfaces can make treatment more difficult. Proper treatment typically involves balancing the water, thoroughly brushing the affected areas, maintaining the appropriate sanitizer level, and using a product specifically intended for black algae.
⚠️ Don’t ignore those black spots!The longer black algae is allowed to establish itself, the more difficult and time-consuming it can be to remove.
