The secret to crystal-clear hot tub water is not spending hours every week with test strips and bottles of spa chemicals. Instead, it comes down to a few consistent habits and understanding how Colorado’s climate affects your spa.
If you’re planning to buy a spa or you’ve recently become a new owner, learning the basics of hot tub water care will help you enjoy cleaner water, protect your investment, and reduce unexpected maintenance.
Colorado’s Climate Can Affect Your Water
Colorado presents a unique environment for hot tub owners. Dry air, sunny days, cool nights, and changing seasons can all influence water chemistry.
Water naturally evaporates more quickly in Colorado’s low humidity. While the water itself leaves, dissolved minerals remain behind, which can gradually increase calcium hardness and total dissolved solids over time. Topping off the spa with fresh water helps replace lost water, but regular testing is still important to keep the water balanced.
Leaves, dust, pollen, and wind can also introduce debris, making a quality hot tub cover one of the simplest ways to keep your spa cleaner between uses.
1. Test Your Water Every Week
Regular water testing helps catch small changes before they become bigger problems.
Spa owners should check:
- Sanitizer levels
- pH
- Total alkalinity
- Calcium hardness
Keeping these values within the manufacturer’s recommended ranges allows your sanitizer to work properly while helping protect hot tub equipment and surfaces.
2. Use the Right Amount of Hot Tub Chemicals
Adding more spa chemicals does not always produce better water.
Follow the dosage for your hot tub’s water volume, and give products time to circulate before testing again and making additional adjustments. Small corrections are usually more effective than large ones.
If you’re ever unsure which hot tub chemicals are appropriate for your spa, as your local Castle Rock and Denver hot tub dealer, we are happy to recommend products designed specifically for your water care system.
3. Don’t Forget Your Filters
Filters do much of the hard work behind the scenes.
Give them a quick rinse every week to remove dirt and debris, spray them with hot tub filter cleaner and then rinse once a month, and give them a deeper clean by soaking them in filter cleaner about once a quarter. Having a spare hot tub filter on hand allows for an easy swap and little downtime whenever it’s time for a deep clean. Of course, be sure to also refer to your manufacturer’s schedule.
A clogged filter reduces water circulation, making it more difficult to keep water clean. Replacing filters as recommended also helps maintain good performance throughout the life of your spa.
4. Keep the Cover Closed
Your hot tub cover does much more than hold in heat. It helps keep out dirt, insects, leaves, pollen, and blowing dust, all of which can affect water quality. It also reduces evaporation, helping maintain water levels while lowering heating costs.
A well-fitting cover is one of the easiest ways to simplify water care throughout every season.
5. Fresh Water Still Matters
Even with excellent filtration and good water care, every hot tub eventually needs fresh water.
Body oils, lotions, dissolved minerals, and sanitizer byproducts gradually build up over time. Most manufacturers recommend draining and refilling the spa every three to four months, although usage levels may shorten or extend that schedule. And stretches of cold weather make timing important.
Fresh water provides a clean starting point that makes balancing your water much easier.
