Product Overview

Black Algaetrine is a powerful, fast-acting algaecide formulated specifically to eliminate stubborn black algae—one of the most resilient and unsightly forms of algae in pools. Infused with copper-based agents and deep-penetrating infiltrators, Black Algaetrine targets algae at its root, breaking down protective layers to kill existing growth and prevent future outbreaks.

Compatible with chlorine, bromine, and ozone systems, this specialized formula allows for swimming without wait time after application. Whether used as a spot treatment or part of a routine maintenance plan, Black Algaetrine is your go-to solution for aggressive algae control in all pool types.

How to Use:

  1. Brush visible algae before application to loosen buildup.

  2. Ensure pool pH is between 7.2–7.8 for best results.

  3. Apply 6 oz per 10,000 gallons of water directly along the pool edges, distributing evenly.

Key Benefits:

  • Destroys tough black algae at the source

  • Swim immediately after use

  • Compatible with all common pool sanitizers

  • Ideal for both treatment and prevention

Active Ingredients:

  • Copper Ethanolamine Complex: 9.5%

  • Ammonium Chloride: 26.3%

  • Other Ingredients: 64.2%

Common Questions & Instructions

Should I add this while the pump is off?

No, targeted chemicals require thorough circulation. Keep your pump running for at least 12-24 hours after application.

Can I swim immediately after dosing?

We generally recommend waiting at least 2-4 hours after adding specialty chemicals, or until the entire volume of pool water has turned over once.
