Having a hot tub or spa right in your backyard is a perfect solution for the stress of a long day. Not only are they great for soaking, but they can also be therapeutic and relaxing. While having access to this luxury is a huge plus, it’s important to keep the spa water clean and healthy. Clean spa water not only improves the life expectancy of the unit but it also saves time and money in the long run. In this article, we will discuss the best practices for keeping your spa water clean and healthy.

1. Maintain A Proper pH Balance

Test the Water Regularly

The water in your spa should have a pH level between 7.2 and 7.6 in order to be safe for bathing. This means testing the water regularly with a chemical testing kit that is readily available at most home improvement stores. Weekly testing is recommended, but it’s best to test every other day to ensure the proper balance is maintained.

Adjust pH Level

If the pH balance is off, it should be adjusted immediately. This can be done by adding a pH balancer to the water. There are a few different types available, but the most reliable options are phosphate-free and buffered balancers. For proper application, follow the instructions on the package.

Add An Enzyme

Adding an enzyme to the water every few weeks can be a great way to help keep the pH balanced. Enzymes can help break down and dissolve organic matter as well as help protect the surface of the spa from scale build up.

2. Clean the Filter

Check Filter Monthly

Your spa filter helps keep the water clean by trapping dirt and debris. It’s important to check the filter monthly and clean it if necessary. You can clean the filter with a hose or a chemical filter cleaner. To ensure the maximum lifespan of the filter, it’s best to replace them every 2-3 years.

Microfiber Filters

For best results and the most efficient filter, many spas are now equipping microfiber filters. Microfiber is made up of very small fibers that are smaller than even a single micron. These small fibers help trap more debris and keep the water clean.

Granular Filter Cleaner

Another great way to clean a filter is to use a granular filter cleaner. This is a unique chemical filter cleaner that is added to the water and slowly dissolves over time, loosening and removing any debris that is trapped in the filter. For best results, use a granular filter cleaner once a month.

3. Sanitize Regularly

An Easy Way To Sanitize

The best way to keep the water in your spa clean and free of bacteria is to use a sanitizer. This can be done in the easiest way by using an automatic sanitizer, such as chlorine, bromine, or ozone. These sanitizers work to maintain a healthy level of bacteria, so the water is safe for use.

Cleaning Accessories

In addition to using a sanitizer, it’s important to clean the spa and any accessories that touch the water on a regular basis. Towels, robes, toys, and covers should all be cleaned with a mild detergent and water on a regular basis. This will help keep the water clean and free from any dirt or debris.

Shock The Water

Shocking the water on a regular basis is also a great way to keep it clean. This involves adding a special chemical to the water to help get rid of any bacteria or oils that have built up. This should be done every week to keep the water safe and clean.
