    Phosphates are terrible for the environment as they pollute lakes, streams, and other natural bodies of fresh water and phosphates can also build up in pools. Because phosphates are a regular contaminant of pool water, it’s even present in rain, and because phosphates don’t break down naturally it is important to use Phos Free for swimming pools. In fact, eliminating phosphates eliminates waterline ring in your pool and Phos Free eliminates phosphates effectively so that your pool is free of cloudy water and unsightly waterline rings.
