Leisure Time Calcium Booster

Although the pH and total alkalinity measurements are the same, the sanitizer level (bromine or chlorine) should be kept between 3-5 ppm. In a spa, the filter requires more frequent cleanings. In addition, the water will require more frequent care to assure pH and sanitizer levels are correct. For further details, please see our spa care guides.

Controlling the pH in a spa can be challenging. Using Leisure Time^® pH Balance Plus every time the spa is refilled will lock the pH in the proper range until the spa is drained again (usually 90 days).

It is recommended that you add this “bank” in order to ensure that the sanitizer in the water is all bromine from the moment you first start using it.

Too little calcium in the water can cause foaming and corrosion, particularly in heaters and other metal components. To increase the hardness to the recommended level of 150-400 ppm, add a calcium hardness increaser such as Leisure Time^® Calcium Booster. Too much calcium can cause scaling on the walls and heating elements or cloudy water. To prevent calcium in the water from causing these problems, add a sequestering agent such as Leisure Time^® Defender.

Ozone is a highly reactive oxidizing agent. Some people are under the impression that ozone will destroy clarifiers and make them ineffective. We have found, however, that ozone does not affect the effectiveness of clarifiers. Clarifiers do provide a very real benefit in ozonated spas by helping the filter keep the water clean.

The dishwasher may damage the fabric on the filter. The best way to clean your filter is to soak it in a bucket of water with Leisure Time^® Filter Clean. This will ensure that all oils, lotions and minerals will be removed from the filter. For quick cleanings, use Leisure Time^® Instant Cartridge Clean.
