Product Description

Manufacturer Description

Why use PHOSfree?

Your pool water is constantly being invaded by phosphates.
What are phosphates?

Phosphates are a primary nutrient or food source for algae*.
If you starve algae of this important food source, it cannot grow.
Phosphates enter your pool from a variety of sources, including: lawn & garden fertilizers, chemicals & cleaners, rainwater & fill water, body fluids & waste, decaying vegetation and the list goes on...

These phosphates build-up in your pool water, providing a necessary food source and bloom environment for algae. Typically, algae is treated with harsh chemicals like algaecides or other sanitizing products. This is where PHOSfree shines.

Natural Chemistry’s PHOSfree continually removes phosphates as they enter the water, keeping phosphate levels to near zero. This allows normal sanitizer levels to prevent algae growth.

Another great benefit to PHOSfree is it is non-toxic and 100% safe for your family and the environment!

*Algae Free Guarantee is provided exclusively by this products manufacturer (Natural Chemistry).
