Chlorine Demand

Chlorine Demand: The inability to maintain a free chlorine residual in the pool water.

PROBLEM: Continuous addition of free chlorine fails to raise sanitizer level in pool water. Test kit reading shows low-to-no sanitizer level.

SOLUTION: Make sure filter runs for a minimal of 10 hours per day, longer in hot weather and heavy bather loads. Make certain test reagents are fresh and unspoiled. Check for inadequate product levels in skimmer, floater or chlorinator. Make sure chlorinator tubing is free from obstructions.

PROBLEM: Algae presence.

SOLUTION: Algae growth will cause a drastic increase in chlorine consumption. If algae is present, refer to the Algae portion of this guide and use products such as Algae Terminator.

PROBLEM: Improper chemical balance.

SOLUTION: Take a sample of your pool water to your OMNI® Dealer for a complete analysis. Follow recommendations.

PROBLEM: Undetectable organic contamination, i.e., improperly applied fertilizers, pollens, migrating birds.

SOLUTION: OMNI Dealers have a chlorine Demand Test Station. This test will tell you exactly how much free chlorine is required to overcome the pool's demand.
