The "Nitrogen Cycle" is a cycle that occurs in nature and must occur in your pool to achieve water quality. If the cycle is interrupted, problems often arise, i.e. fish problems, algae blooms, etc. Testing for water quality that involves the Nitrogen Cycle is important. These results are important in diagnosing problems that arise in water gardens. The Ultra Clear products, containing the "good" bacteria, are very important to use as a routine additive to keep the water clear and healthy.
