  •   What is black algae, and why is it a problem in pools?

    Black algae is a stubborn and tenacious form of algae that commonly forms in swimming pools. It appears as dark, blackish-blue, or green spots that can be difficult to remove. Black algae can penetrate pool surfaces and establish deep roots, making it challenging to eliminate. It can also create an unsightly appearance and rough texture on pool walls and floors.

  •   Is a Blackspot granular Algaecide treatment more effective than liquid treatments for black algae?

    Both granular and liquid treatments can be effective against black algae, but Blackspot Granular Algaecide treatments are often favoured due to their targeted application. Granules can be directly applied to the affected areas, allowing for better control and concentration of the treatment on the black algae spots. This can result in more efficient eradication of the algae.

  •   How does a granular black algae treatment work?

    Blackspot Granular Algaecide algae treatment is a specialised pool chemical designed to target and eradicate black algae infestations. When added to the pool water, the granules dissolve and release the active ingredients, which work to destroy the algae and prevent its growth.
