Hot Tub Maintenance Checklist: 6 Steps to Soaking in Your Spa

Ahhhh, hot tubs. Whether you’re just thinking about buying one or are already proud owners, there’s something about the idea of a hot soak in a relaxing tub that appeals to just about everyone. 

And what’s not to like about the idea of slipping into a soothing hot tub after a hard day at home or the office? Or enjoying family time as you soak and connect at the end of the day? The benefits of using a hot tub are real: it can help soothe your aches and pains, improve sleep, reduce stress, and more.

Most potential and new users have questions about hot tub maintenance and Zagers experts have the answers. You can call us anytime to pick our brains or schedule an appointment to have Zagers help with your hot tub maintenance

If you prefer to tackle it yourself, here’s a hot tub maintenance checklist to help you do so. We hope it will ease your worries about hot tub maintenance costs (they’re fairly low) and hot tub maintenance time (it’s fairly low, too) so you can simply enjoy soaking your other worries away.

Chemistry is key.

The first and most important part of hot tub maintenance is keeping your water clean (sanitized) and balanced. Fortunately, this step is both easy and relatively inexpensive. 


First, test your spa water once a week with a strip that checks its levels of pH, chlorine, calcium hardness, and total alkalinity. Next, adjust the levels as necessary. Properly balanced hot tub water will fall within the following ranges:

·       Chlorine: 1.0-3.0 ppm (when using with a mineral sanitizer or ozonator)

·       pH: 7.2-7.6

·       Total Alkalinity: 125-150 ppm

·       Calcium Hardness: 100-200 ppm 

Not sure about testing or balancing your water on your own? Bring a water sample in to any Zagers location and we’ll professionally test it and provide advice on maintenance and balancing your water.

Maintain the water level

Keep an eye on your water level – make sure the water is high enough for proper filtration, the ability to heat the water, and jet performance. This is typically a few inches above the filter. You also do you want to risk an overflow because the water level is too high (keep in mind that the water level will rise when people are in the hot tub.) Just like baby bear in the Goldilocks story, you want it to be “just right.” Drain or add water as needed, and you’ll be just fine!

Clean your hot tub weekly

Although it’s a weekly chore, this one’s fairly simple. If your hot tub is outside, you’ll need to skim the water to remove any debris.

Beyond that, whether it’s indoors or outdoors, you’ll want to wipe down the shell, waterline, and jets once a week with a non-abrasive sponge and cleaner (we like BioGuard’s Off The Wall surface cleaner that is safe to use on hot tub surfaces).

Drain and refill your hot tub once per quarter

While a weekly wipe down is a key component of hot tub maintenance, you’ll also want to completely drain and refill the water every three to four months, depending on your usage. While it’s empty, it’s a good idea to do a thorough cleaning of the entire tub—once again with Off The Wall.  

Show Your Spa Filter Some Love

Your hot tub filters work hard, circulating water and keeping it free of contaminants. Help them do their job by keeping them clean, too.

Once a week, when you clean the surface of the tub, locate and remove your filter(s) and give them a good rinse with regular water. We recommend using a cartridge filter cleaning nozzle that attaches to a garden hose to rinse between the filter pleats. Place the filter(s) back in the hot tub when done. These nozzles can be found at any Zagers location.

Then, on the day you drain and refill your tub, give your filter a deep clean by soaking it in a degreasing agent that is designed to remove body oils, debris and residue.  One of our favorites is BioGuard’s Kleen It.

As part of your hot tub maintenance, you should completely replace your hot tub filters every year or two. We also suggest always keeping an extra set on hand so that you can rotate the filters. Not only will they last longer, but you can continue to enjoy your hot tub while the second set is being cleaned.

Give Your Cover a Breather

Spa covers endure a lot of heat and moisture, which might sound great to you but isn’t always best for a vinyl cover. To add life to your investment, remove your cover once a week and air it out. To clean and rejuvenate the vinyl on your cover, we recommend using a marine vinyl cleaner & conditioner or a 303 aerospace protectant.

That’s it! Doing these six things will help you enjoy your hot tub week after week, month after month, and year after year. The overall hot tub maintenance cost and hot tub maintenance time are relatively low. They help your initial investment provide plentiful returns by giving you a soothing respite from the cares of the world. Then, it the end of the day, when you slip into your well-maintained hot tub, all your worries can float away as the jets work their magic and your tension dissipates. If you’d prefer to have the experts at Zagers provide hot tub maintenance for you, we’d love to help. This service is quite popular, though, so be sure to contact us for information and get on our schedule as soon as possible. We look forward to serving you!
