Why is the water in my Spa cloudy? As professionals, this is a question Spa/Jacuzzi owners will often ask us. The answer (or better yet answers) is that there are a more than one reason for this and therefore solutions:

Before we begin... Look for your Spa Owner's manual, it'll come in handy!! 1. IS YOUR SPA CIRCULATING ENOUGH? With your owner’s guide manual in hand, look for the listed appropriate filtration times for your spa model, size, specs… Or ask your local spa provider.

2. ARE YOUR SPA FILTERS CLEAN? It's pretty common to neglect your spa’s filters, which are essential to maintain your water crystal clear. For a correct maintenance of the water, Spa filters need to be washed off weekly. We suggest rinsing the filter with a hose with pressure but without damaging the filter material. We also suggest to soak your filter in an approved spa filter cleaner every two months in order to eliminate body fats and other organic matter that cannot removed by simple rinsing, this will increase the life of the filter. Most of our costumers rotate 2 sets of Spa filters so that they can soak one set while the other is in use. Note, you should always follow the guidelines of your filter cartridge cleaner label. Do not use products that may contain traces of bleach, as it will reduce the length of the life of your spa filters. Important: Purezone filters cannot be washed and must be replaced at least every three months based on bather load. 3. ARE THE pH LEVELS AND ALKALINITY OF THE WATER IN YOUR SPA WITHIN THE "REASONABLE" RANGE? The pH and Alkalinity in your Spa should be within this scope (on your test strips) pH 7.2- 7.8 Alkalinity 80-120. If not, modify up or down using an approved pH reducer or Alkalinity increase until it is appropriate. Make sure to do as instructed and give the substances a chance to work before examining again. Email Us. 4. ARE YOU SHOCKING YOUR WATER ONCE A WEEK? You need to use an approved oxidiser at least once a week or after a heavy use. Spa shock oxidises the organic matter that makes the water cloudy. Important: If you are using a chlorine free sanitising system you will need to shock the water with a chlorine free shock go through guidelines on the brand. (For more details contact us directly) 5. ARE YOU FOLLOWING YOUR SPA MANUFACTURER USE OF CHEMICAL INSTRUCTIONS? Make sure you are dosing your spa water with enough Sanitiser. Under dosing your Sanitiser can cause cloudiness.

6. TYPE OF WATER USED FOR YOUR SPA. If you are using rainfall water and have followed the recommendations above but your water is still a a little cloudy you may use a water clarifier or flock. Study the guidelines for dose rates. Essentially the water clarifier works by grabbing microscopic particles of organic matter and combining them into larger particles where they can quickly be captured in the filtering system.
Important: If you use Purezone spa filters, follow the dosing instructions so that you do not prematurely plug your filter. Spa chemicals take time to work. Be patient.
