WATER QUALITY

KEEPING YOUR SPA WATER CLEAR AND FRESH

Important! Keep the spa covered when not in use!

This information is for new spa owners with no experience with water chemistry. Everyone’s experience with maintaining water quality is different, but there are some general concepts you need to know.

Water maintenance is not difficult, although it requires regular attention. The most important thing to understand about taking care of your spa water is that preventive action is much easier than correcting water quality issues.

Excellent water quality is a simple matter of four things:

1. Chemical Balance

Chemical Balance

Chemical Balance You will need to test and adjust the chemical balance of your spa water. Although this is not difficult, it needs to be done regularly. Depending on your choice of sanitizer, you need to test the level of calcium hardness, total alkalinity, and pH. Spa owners with a Cal Clarity II bromine generator also need to check total dissolved solids and phosphates.

2. Sanitation

Sanitation

Sanitizers kill bacteria and viruses and keep the water clean. A low sanitizer level will allow microbes to grow quickly in the spa water. We recommend using either chlorine or bromine as your sanitizer.

Spa owners with an ozonator or the Pure Cure system also need to add sanitizer, although their requirements are different.

3. Filtration

Filtration

Cleaning your filter regularly is the easiest and most effective single thing you can do to keep your water clear. A clogged or dirty filter will cause the heater and pump to work harder than they need to, possibly causing them to fail.

The spa’s heating system will only function with the proper amount of water flow through the system.

4. Regularity

Regularity

Clear water requires regular maintenance. Establish a routine based on a regular schedule for your spa water maintenance.

Maintaining your water quality helps the enjoyment of your spa and extends your spa’s life by preventing damage from neglect and chemical abuse.
