      About Applied Bio

      When standard chemicals fail, pool professionals turn to Applied Biochemists. With a history dating back to 1965, this brand has established itself as the "emergency room" for swimming pools. They don't just sell generic sanitizers; they engineer targeted solutions for the industry's toughest problems—from stubborn Black Algae and chlorine-resistant Mustard Algae to complex mineral stains.

      Applied Biochemists is renowned for their "color-coded" approach to algaecides (Yellowtrine, Black Algaetrine), ensuring you treat the specific root cause rather than guessing. If you are battling a persistent issue that won't go away, this is the professional-grade intervention your water needs.

      Why We Trust Applied Bio
      Symptom-Specific Formulations: Specialized treatments for distinct algae types (Green, Yellow, Black) rather than "one-size-fits-all" fixes.

      Professional Strength: High-concentration active ingredients designed to resolve issues faster than big-box store alternatives.

      Mineral & Stain Experts: Industry leaders in sequestering agents that prevent metal staining and scale buildup.

      Non-Foaming Solutions: Many of their algaecides are engineered to work without causing messy foam, even in spas or water features.
