In The Swim Algaecide

Standard algaecides often struggle with black algae because of its protective, waxy coating. This formula uses 11.8% copper sulfate pentahydrate specifically to penetrate that tough defense, making it much more effective against stubborn black algae blooms than general-purpose treatments.

Preparation is critical for this product to work. You must brush the affected pool surfaces to break up the algae, clean your filtration system, and super chlorinate the water before applying the algaecide.

Yes, it functions as both a targeted treatment for existing blooms and a preventative maintenance tool. Using it regularly can help stop black algae from taking hold in the first place.

You should wait until your chlorine levels drop back down to a safe range of 3-4ppm before entering the water. Always test your water chemistry after treatment to ensure it has returned to safe swimming levels.

While effective, copper-based algaecides can sometimes cause staining on certain pool finishes if not used correctly. It is best to follow the dosage instructions precisely and ensure proper water circulation to minimize any risk of staining.
