Dealing with Excessive Chlorine Loss

What to Do About Excessive Chlorine Loss

Well, it’s hot, but you already knew that. And, so does your swimming pool.

When it is excessively hot here in Oklahoma, pools can experience excessive chlorine loss. This is especially true on extra sunny days with no clouds. But, you do have options, and you can enjoy a crystal clear, clean pool.

What is Excessive Chlorine Loss

This happens when your pool has a consistent inability to maintain chlorine levels. You may have heard this referred to as chlorine demand.

When you have a high level of inorganic and organic contaminants in the water, you will end up with chlorine demand.

Why? These contaminants force the chlorine to work extremely hard to oxidize them, leaving little chlorine to protect your swimmers. Proper chlorine levels cannot be reestablished without first eliminating the contaminants.

External factors such as sunlight and heat contribute to this chlorine loss because bacteria grows better when it’s hot. As the bacteria multiply, your  pool uses up your free chlorine.

In addition, sunlight causes a loss in free chlorine because as the ultraviolet rays shine on your pool, the chlorine is released as a gas. You can experience a huge loss of chlorination in your pool in just a few hours on the sunniest days.

Proper pool maintenance can help prevent and alleviate the problem.

How to Fix Chlorine Demand

First, you want to bring us a sample of your water. We can run it through our free ALEX computerized system to determine the extent of the chlorine demand.

Then, we may recommend specific products such as one of BioGuard’s BurnOut products to clear your problems.

How to Prevent Excessive Chlorine Loss

To prevent the problem in the first place, we recommend using BioGuard Pool Complete. Use this in your weekly maintenance routine to reduce contaminant levels. We also recommend the following:

  • Maintain an appropriate sanitizer residual of 1-3ppm
  • Shock/oxidize routinely or as needed depending on bather load
  • Test water frequently and adjust as needed
  • Routinely check for circulation and filtration issues
