Enzymes and Your Swimming Pool

By Debbie - Updated On: 05/01/19

Royal Swimming Pools would like to tell swimming pool and spa owners a little information about enzymes and how they can help keep your swimming pool water in excellent condition over the winter months.


According to the dictionary, Enzymes are protein molecules that help other organic molecules enter into chemical reactions with one another but is unaffected by these reactions. In other words, enzymes act as catalysts for organic biochemical reactions. Enzymes are produced by living things but are not alive so they cannot be killed. Enzymes can help destroy organic contaminants in your swimming pool or spa water. There are two types of enzymes and they are either natural or synthetic. Natural enzymes are usually more stable than synthetic or man-made enzymes.

When enzymes are used with chlorine or bromine, they help to extend the use of other chemicals. Which means, you will be using less of the more harmful chemicals in your pool. In turn, your swimming pool water will not be as harsh on the swimmers skin, eyes, and hair. Enzymes are also a very effective way to keep stains out of your pool over the winter months. These stains are caused by natural oils left in the pool by swimmers. Those natural oils float to the top of the water and combine with other dirt in the pool, which causes an ugly water line stain. The enzymes will eat away at any organic items in the pool and keep that dirty water line from developing on your pool or spa wall. Enzymes are very effective in keeping your pool and spa filters cleaner as well.

Royal Swimming Pools offers several natural enzyme treatments. The two most popular are Winterball and Pool Magic. You can use either by themselves, or in conjunction with your regular winterizing chemicals. Winterball is an all natural enzyme formula that slowly releases all winter long to help keep your pool clean and clear. One Winterball will treat up to 30,000 gallons of water, and is safe to use in all pools and spas. Pool Magic contains a concentrated natural enzyme based formula designed specifically to work in cold water. It quickly breaks down organic contaminants, and cleans up cloudy and dirty pool water. It treats up to 25,000 gallons.

Try out an enzyme treatment this winter and see just how clean it keeps your pool!
