Spa FAQs

Maintaining your spa should be as worry-free as possible, but sometimes questions arise. When they do, Leisure Time® is here to help, every step of the way.

Ease your mind and find answers to commonly asked questions below. And if you don’t see exactly what you need, don’t hesitate to contact us for more information.

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.

When the pH and the total alkalinity are opposite of one another, always fix the low number first. In this case, add a pH increaser until the pH is within a normal range. Then, adjust the total alkalinity by adding a pH level reducer. Using Leisure Time® pH Balance Plus after this will lock your pH into the proper range.

The white chips are calcium deposits (scale which forms on the heater elements) which are knocked off when the blowers and jets are on. This problem may be prevented by using a sequestering agent, such as Leisure Time® Defender, on a weekly basis to prevent calcium in the water from forming deposits.

Non-chlorine shock for pools is not buffered and may affect the overall water chemical balance of the spa water. It is best that you use a non-chlorine shock, such as Leisure Time® Renew, designed specifically for spas. This will help reduce the need for extra chemical treatment to keep pH in the proper range.

There are several reasons that a spa foams. A common cause is the rapidly moving water combined with bathers bringing in soaps and detergents on their bodies and bathing suits. Showering before entering the spa helps prevent this problem. If excess detergents are the cause of the foam, using a defoamer such as Leisure Time® Foam Down will reduce the amount of foaming.

Another cause of foaming is soft water. This means that the calcium level in the water is low. This can be corrected by raising the calcium level to 150-400 ppm.

Organic waste build up can also cause foaming. By shocking the spa on a regular basis, the wastes are oxidized out of the water and foaming is reduced.

Overall, bromine tends to be more popular among spa owners. Bromine is offered in both a tablet form and as a two-part system. Unlike chlorine, bromine is effective over a wider pH range, doesn’t irritate your eyes or bleach bathing suits. Additionally, bromine is effective in its combined form, doesn’t smell and is an effective sanitizer.

Many spa owners however, elect to sanitize with chlorine. It is traditionally used in pools, and it is an effective sanitizer and oxidizer. Granular chlorine is the easiest form to use and will keep the water sparkling clean!

How often you shock spa water depends on the sanitizer used and the bather load. If you are using the 2-part bromine sanitizing system such as Leisure Time® Reserve and Renew, it is recommended that you shock each time you finish using your spa. If you are using chlorine or bromine tablets, it is recommended that you shock at least one time per week. It may be necessary to shock more often if the bather load is heavy or the water is cloudy.

Yes. Even though ozone is an effective oxidizer and will even destroy microorganisms directly exposed to the ozone, the ozone is relatively short lived in your hot tub water. As such the ozone is not present in the water for a sufficient length of time to assure adequate sanitation of the entire tub and the surfaces and plumbing. The use of an ozonator will reduce your consumption of chlorine or bromine as it makes it easier to maintain proper levels of these in the water it does not eliminate their usefulness.

Absolutely. Water that is low in calcium hardness can be corrosive to other metal parts in your spa, particularly your heater. We recommend maintaining a calcium hardness level of 150 – 400 ppm. Maintaining proper calcium hardness levels will also help reduce foaming.
