Fast & Easy Pool Start-Up

Natural Chemistry Pool Magic + PHOSfree provides quick and easy pool openings in the spring, reducing waterline ring and phosphates in the water. Pool Magic features a blend of enzymes to break down oils and other non-living organic contaminants for cleaner feeling water. It also contains PHOSfree which is great to use to reduce a moderate amount of phosphates to help prevent future algae blooms.

Clear Cloudy Water Fast

In The Swim Clarifier for swimming pools helps coagulate dirt and other suspended particles clearing cloudy pool water. Adding In The Swim Clarifier also increases your pool filter's efficiency. Fast acting and biodegradable, this water clarifier does not affect the chemical balance in the pool.
