Natural Chemistry Pool and Spa Water Care

About Natural Chemistry Pool and Spa Water Care

Founded in 1989, Natural Chemistry shifted the paradigm of pool care by asking a simple question: "Is there a better, more natural way?" While the rest of the industry relied heavily on harsh industrial chemicals, Natural Chemistry pioneered the use of powerful, naturally based enzymes—similar to those found in your own body—to break down organic waste.

What started as a single enzyme formula to combat scum lines has grown into North America’s leading authority on specialty pool water care. Their philosophy is built on "biomimicry"—using technologies inspired by nature to solve common pool problems like algae fuel (phosphates) and greasy buildup. By breaking down contaminants rather than just masking them, their products often reduce the need for excessive sanitizers and scrubbing. For the DIY homeowner, Natural Chemistry represents the "work smarter, not harder" approach to maintenance, delivering high-end results with eco-conscious science.

Why We Trust Natural Chemistry Pool and Spa Water Care
Pioneering Enzyme Technology: They were the first to successfully stabilize natural enzymes for pool use, allowing water to "digest" oils, lotions, and pollen naturally.

Problem-Solving Focus: Rather than generic fixes, they manufacture targeted solutions for specific headaches, such as high phosphates (Phosfree) or persistent scum lines.

Efficiency & Simplicity: Their core promise is to reduce maintenance time and effort, polishing water so it sparkles without constant manual labor.

Eco-Conscious Chemistry: By removing organic load efficiently, their products often help sanitizers work more effectively, potentially lowering the total chemical burden in the pool.
