How to Maintain a Swim Spa


A swim spa is more than a pool of water, it’s a health installation and a cardiovascular workout in progress. Whether you’re looking to lose weight, stay in shape, or simply relax, a swim spa may be exactly what you need. Like all other pool equipment, these pieces require maintenance.

It’s important to know what the requirements before you buy. Pools that receive poor care are a health and safety risk, and serious neglect could require expensive repairs. You’ll have to invest some time in maintenance. Thankfully, the payoff is worth it. Here are some basic tips for maintaining a swim spa.

Check the Water

Even if you aren’t using it daily, you should at least be checking the water in the pool. Keep track of how it looks and smells. Changes in these two things could be symptoms of developing problems that you can take care of early. Problems with filtration, for example, are always easier to remedy when the entire filtering system hasn’t been compromised.


The chemistry of a pool shouldn’t be daunting. There are simple methods and devices that can help you keep track of things like calcium hardness, chlorination, and pH. You should try to keep the pH close to that of the human eye – 7.4. This will reduce irritation if you are swimming without eye protection.

Chlorine is ideal at a ratio of about 3 parts per million, though a range of one to five is acceptable. Calcium hardness should be kept between 125 and 400 parts per million, with total alkalinity around 160 parts per million. This will keep the water in the pool safe to swim in, and ensure that it isn’t corroding the filtration and heating systems.

Test Strips

Test strips are the simplest tool for tracking your spa chemistry. Frequently, manufacturers advice that if you can’t get everything in balance at once, you focus on pH and chlorination. As your experience increases, your ability to manage levels will also improve. Don’t be discouraged if you don’t get it perfect in the first go. Make sure it’s comfortable, then improve it over time.

Changing the Water

Completely draining and refilling your tub every 3 to 6 months, depending on use, will help you be certain that the water is always clean and safe. Continually adding chemicals to the water can cause buildup in the pipes that support your swim spa. It may be a hassle, but fully replacing the water will do wonders for the life of your spa, and the quality of the time you spend in it.

Temperature, Economy, and Showers

Every public pool and hot tub asks that people shower before entering, and your home equipment should be no different. As a way to lower operating and heating costs, you should run your swim spa in economy mode when not using it on a regular basis (ie. daily or weekly).
