CrystalClear OneFix®



CrystalClear® OneFix™ utilizes natural bacteria to digest suspended dead organics to help keep the pond balanced and the water crystal clear.  CrystalClear® OneFix™ is specifically designed to start working the second it hits the water.

Use when water temperatures are above 50°F.

When To Apply OneFix™:

CrystalClear® OneFix™ can be applied to remove ammonia, nitrite, nitrate, and organic debris that can lead to water clarity problems.  CrystalClear® OneFix™ is best used when water temperatures are above 50° F with aeration.

How To Apply OneFix™:

Routine Application Rate: Apply CrystalClear® OneFix™ every 2 weeks. For initial treatment of a new pond prior to adding fish, double the application to seed pond quickly and to avoid “new pond syndrome”. Do not use with any other chemical.

Persistent Problem Application Rate:  Apply once a week or every 3 days for persistent problems as needed.
