Is your pool looking cloudy and sickly?
Your pool could be suffering from a Chlorine Demand.
Before we jump into Chlorine Demands, lets first understand what having a Free Chlorine Residual means.
Free Chlorine is the active chlorine in the water that has not combined with organic matter and is therefore available for killing bacteria and algae. The proper range for free chlorine residual is 1-3 ppm. Below 1 ppm can cause swimmer irritation, cloudy water, chlorine demand, and even allow algae to grow. If you are having trouble maintaining 1-3 ppm of Chlorine, you may be in a demand.
So what exactly is a Chlorine Demand?
A Chlorine Demand is the consistent inability to maintain a free chlorine residual in a pool. It is caused by a build up of contaminants which creates and “overload” on the sanitizing system. Quite simply, it means that more sanitizer is required that is being provided to the water.
There are two ways to treat chlorine demand. The first is to add the appropriate amount of chlorine. The quickest way to find out what that amount is would be to have one of our BioGuard Certified Water Care Experts right here at ASAP run a chlorine demand test on the Accu-Demand30®. This test is the most accurate test in the industry to find out exactly how much shock you will need to break your Chlorine Demand.
Depending on the severity of the Demand, the test results will tell you you’ll need to add any amount of shock from 5lbs to 100lbs. In most cases, you can use BioGuard Pool Tonic in conjunction with CLC3 to lower the amount of shock you will need to use.
As mentioned earlier, a Chlorine Demand is a build up of contaminants. Pool Tonic will remove a large portion of those contaminants, thus lowering the amount of shock needed to burn them off and establish a Free Chlorine Residual.
Once we have helped you break your chlorine demand and you are maintaining a steady 1-3 ppm of Free Chlorine, you may resume your normal BioGuard System.
