How To Maintain A Swim Spa : A Complete Guide

15 December, 2021
Swim spas are a wonderful addition to any backyard, however maintaining a swim spa is essential to keeping it in good condition and functioning properly. At periodic times the water should be replaced and filtration system cleaned. The acrylic surfaced should be wiped free of dirt or debris and inspected for permanent marks or scratches. The cedar cabinets can also be lightly sanded and re-polished and even the hardcover itself, which is designed to protect the spa should be taken well care of so that it may continue to serve it's purpose. This all might seem like a lot of work but if you stay on top of things it'll be a breeze and plus, keeping it in good nick will also maintain it's value. This blog post will cover some of the basics of maintaining a swim spa so that you can keep enjoying it for years to come!

Replace the Water in Your Swim Spa (3, 6 and 12 Months)

It's important to replace the water in your swim spa regularly. Over time, chemicals and other contaminants can build up and make the water unsafe for swimming and dirt and grime can also stain or scratch the spas surface. The frequency with which you'll need to replace the water depends on a variety of factors including how often the spa is used and the climate. In general, it is recommended to drain one third of your spa water every three months to refresh your system and maintain good, clean water again, but a full drain every 6 to 12 months. This will be determined by which sanitisation system your spa is fitted with and how often the spa is used. A water test from your local pool & spa store will tell you when its time to drain based on the total number of dissolved solids in the water which can make it difficult to maintain balance of the water and hamper the sanitiser effectiveness. Before draining the water from your spa, first disconnect the power source to be completely safe.

Clean (Fortnightly) and Replace Your Filters (12 to 18 months)

It is important to regularly clean your swim spa filter to keep it running effectively. Swim spa filters remove particles from the water to improve the appearance, clarity, and quality of the swimming experience. Additionally, filters help protect swim spa equipment from becoming clogged or damaged. Swim spa filters typically use a sand or cartridge system to filter out debris. Cartridge filters are often preferred because they are less likely to clog than sand filters; however, they also require more frequent cleaning and replacement. Cleaning your swim spa filters involves removing the filter cartridges once a fortnight, depending on use, hosing them down to remove debris or even soaking them in a filter cartridge cleaner. Depending on use, your filters must be replaced every 12-18 months.

Inspect & Clean The Acrylic Surface

Your Sapphire Spa is manufactured from the highest-grade acrylic material available. A small amount of maintenance is required periodically to ensure that it keeps its finish for many years. The good news is, that acrylic is very easy to clean and generally stains and dirt will not adhere to the surface, however you may wish to wipe down the surface with a soft, damp cloth/sponge and a nonabrasive cleaner (ex. Methylated spirits) after use or during your normal maintenance program.

Maintaining Chemical Balance in Your Swim Spa

Maintaining the right chemical balance in your swim spa is crucial for keeping the water clean and safe, and for preventing damage to the spa's components. You should regularly test the water using a water testing kit, and adjust the levels of chemicals as needed. This includes maintaining the right levels of sanitizer (such as chlorine or bromine), pH, alkalinity, and calcium hardness. If you're unsure how to maintain your swim spa's chemical balance, your local Sapphire Spas dealer can provide advice and guidance.

Safety Precautions for Your Swim Spa

Safety is an important aspect of maintaining a swim spa. You should always keep the area around the swim spa clear of obstacles, to prevent accidents. When the swim spa is not in use, ensure the cover is securely fastened to prevent children or pets from accidentally falling in. Regularly check the cover and other safety features, such as handrails and non-slip surfaces, to ensure they are in good condition.

What you are actually looking for when you inspect the surface are scratches caused by general wear and tear. Sometimes sand or even jewelry can cause scratches to the spa surface. Avoid allowing dirt and sand, caused by bathers entering the spa, simply by placing a mat or foot bath in the entry areas of the spa. This will assist in the easier maintenance of the acrylic surface. If for some reason you notice any stubborn marks, your should consult with your Sapphire Spa dealer for advice on a recommended acrylic surface cleaner. Then once you have received the best advice possible, you may apply something like a car polish or similar product and lightly rub out the scratch in a circular motion.


While inspecting your spa surface you may come along fine hair-like cracks, this is known as crazing. Crazing may occur on acrylic surfaces and appear as fine lines when a spa is exposed to extreme temperatures (thermal cycling) over time even with cover on. Crazing has been called to be an inevitable property of glassy materials so don't stress if you find them, however because they are non-structural it is considered to be a part of natural wear and tear so these are not covered under warranty.

Sunlight & UV Exposure

Sunlight and UV exposure can damage a spa pool surface in a few ways. First, the sun's UV radiation can cause the surface to fade and become brittle. Second, the sun's heat can cause the surface to crack and peel. Third, the chemicals in the water can corrode the surface of the pool. To protect your spa pool's surface from damage, it is important to avoid exposing the surface to direct sunlight for extended periods of time, and make sure that it is properly covered when not in use. Any prolonged period on the acrylic surface may have a detrimental effect on the surface and possibly void warranty.

Cedar & Duratek cabinets (6 to 12 Months)

If you've gone with a cedar cabinet for your spa, you may rest confident that it's built using the highest grade 20mm western red cedar available and has been treated with high-grade, mould-resistant stain. Regular maintenance of the cabinet will preserve the natural appearance of the cedar and guarantee that your spa will always be the focal point in its location for many years to come. To treat your cabinet you will need to lightly sand the timber, then apply a good even coat of stain. Consult your local dealer for the ideal product to stain and protect your cabinet. Small marks and scratches can be treated the same way. The amount of time that wood retains its natural appearance will be determined by the type of care you choose to provide it, as well as the weather conditions. It's possible that if you notice your cedar losing its colour richness, it's time for a re-treatment. Sapphire Spas recommend treatment after 6 months of usage, and then periodically every 12 months. If you own a Duratek cabinet, they must be washed down with a soap and water solution every 12 months.

Making Your Swim Spa More Energy Efficient

There are several ways you can make your swim spa more energy efficient. One of the most effective ways is to use a good quality cover to reduce heat loss. The cover should fit snugly over the swim spa and be in good condition, with no rips or tears. Keeping the water temperature at an optimal level can also help to reduce energy consumption. If you're not using the swim spa, consider lowering the temperature a few degrees to save energy.

Caring For Your Hard Cover

Your Sapphire Spa is supplied with a vinyl, key-lockable hardcover. All hardcovers contain unique heat-sealed foam to prevent moisture retention, which can result in added weight and sagging. Our spa covers are top stitched to add strength and durability and use unique, fully key lockable ABS locks.

Maintaining your hardcover should be part of your regular maintenance routine. Dirt is abrasive to the vinyl and can cause wear to the folds, seams and stitching. Keeping your cover clean is quite simple, but you must follow a routine for cleaning and treatment with a vinyl protector. Your local Sapphire Spa dealer can assist you with ideal vinyl protection.


For long-lasting results we suggest:

• Rinse the cover with cool water using a garden hose.

• Spray with your preferred protectant and wipe clean.

• For stubborn dirt, we suggest a small sponge, similar to one you would use on your car.

• Rinse again thoroughly with water.

• Do not allow children or pets to walk or jump on the hardcover.

• Do not lift or pull your cover by its straps, flaps, skirts or heat seals.

• Never use laundry/dishwashing detergents, abrasives, alcohol-based products or harsh household cleaners. These can actually remove some of the top coat and cause premature vinyl failure.

• Rotate foam inserts if you notice any sagging or water pooling.


Your Sapphire Spa headrests are designed for bather comfort and require very little maintenance. You should remove your headrests to clean behind them when you drain your spa. The headrests are secured by two small lugs at the back and can easily be pulled off with your hands. Thoroughly clean the headrests with a damp cloth or sponge. The headrests are covered by a warranty of two years exclusive only to Sapphire Spas. With care and good chemical balance, your head rests will last many years.
