“Alg Out 40” is a concentrated liquid algaecide specifically designed for swimming pools. Similar to “Alg Out 60”, its primary purpose is to both prevent and eliminate a wide range of algae, including green, yellow, and black. The “40” in its name signifies its 40% concentration, which is a powerful formula for effective algae control.
It is a non-foaming and non-metallic product, making it safe for all pool types and finishes. It works by destroying algae in the water and, when used as part of a regular maintenance routine, it helps to prevent future algae growth.
“Alg Out 40” is typically added directly to the pool water, often around the perimeter. The dosage will vary depending on whether you are using it for a weekly preventative treatment or to combat an existing, visible algae problem. It’s important to always follow the product’s specific instructions and to wait a short period before swimming.
