Hot Tub Maintenance 101: What You Need and When
At Mountain Mist Spa & Sauna in Longmont, Colorado, we believe owning a hot tub should be as relaxing as using one. That’s why we not only help our customers find the perfect spa—like those from American Whirlpool, Vita Spas, and Marquis Spas—but also teach them how to care for it properly.
Whether you’re a new hot tub owner or a longtime spa lover, understanding when and how to perform essential maintenance will keep your spa clean, efficient, and enjoyable all year long. This guide breaks down what you need and when, helping you protect your investment and extend the life of your hot tub.
Why Hot Tub Maintenance Matters
Hot tubs are meant to be stress-relievers, not stress-inducers. Routine maintenance prevents costly repairs and helps your spa:
-
Operate more efficiently
-
Last longer with fewer mechanical issues
-
Provide clean, clear, and safe water
-
Perform at peak levels with strong jets and consistent heat
Whether you’ve chosen the therapeutic comfort of American Whirlpool, the hydrotherapy innovation of Vita Spas, or the sleek design of Marquis Spas, maintenance is the common thread that ensures your spa continues to perform beautifully.
Daily to Weekly Maintenance: The Essentials
Consistency is the secret to hot tub success. These quick checks will help keep your spa in optimal condition every week:
1. Check Water Chemistry (2–3 Times per Week)
Use test strips or a digital testing kit to monitor:
-
pH levels (7.2–7.8)
-
Total alkalinity (80–120 ppm)
-
Sanitizer levels (chlorine, bromine, or other approved sanitizers)
Proper water balance prevents issues like cloudiness, scaling, and skin irritation.
Need supplies? We carry test kits and high-quality spa chemicals at our Longmont showroom.
2. Add Sanitizer (As Needed)
Your sanitizer (usually chlorine or bromine) should be added several times per week, especially after heavy use. This helps kill bacteria and keep your water fresh.
3. Clean the Waterline and Spa Shell (Weekly)
Use a soft cloth and non-abrasive spa cleaner to wipe down the waterline and interior. This stops buildup before it becomes an eyesore—or a problem.
4. Inspect the Spa Cover
Check your cover for mildew, sagging, or cracking. Wipe it down weekly with a spa-safe vinyl cleaner and conditioner to keep it in top shape.
Monthly Maintenance: Keep It Running Smoothly
These monthly tasks help prevent grime buildup and keep your system operating efficiently:
1. Clean the Filter (Every 3–4 Weeks)
Remove and rinse the filter with a garden hose to eliminate debris and oils. For deeper cleaning, soak it overnight in a filter cleaning solution.
American Whirlpool hot tubs feature easy-access filters, and Vita Spas make regular cleaning a breeze. Marquis Spas also support hassle-free maintenance with intuitive design.
We carry compatible replacement filters at Mountain Mist Spa & Sauna.
2. Shock the Water (1–2 Times per Month)
“Shocking” involves adding an oxidizer to remove organic contaminants that sanitizers alone can’t handle. This process helps prevent odors, dull water, and cloudy buildup.
Use non-chlorine shock for regular upkeep, or chlorine-based shock after heavy use.
3. Check Jet Performance
Are your jets as strong as they should be? Any sputtering, reduced flow, or noise could indicate blockage or buildup. Our team in Longmont is trained on all our spa brands and can help you troubleshoot.
Quarterly Maintenance: Fresh Start
Every three to four months, it’s time for a full refresh:
1. Drain and Refill Your Spa
Even the cleanest water needs replacing after several months of use. Empty the spa, clean it thoroughly, and refill it with fresh water.
2. Clean the Shell and Jets
Use a spa-safe, non-abrasive cleaner to scrub the shell, jets, and any tight areas. Be sure to clean under removable pillows or covers too.
3. Flush the Plumbing Lines
Run a line flush treatment through your system before draining to eliminate buildup inside pipes. Even models like Marquis Spas, which offer advanced filtration, benefit from this extra care.
4. Inspect Components
This is a good time to look for wear and tear on pumps, heaters, lighting, and the control panel. Our technicians are happy to inspect your spa or schedule service if needed.
Annual Maintenance: Long-Term Health
Once a year, take your maintenance routine to the next level:
1. Replace the Filter
Even if you clean it regularly, your filter should be replaced annually for maximum effectiveness.
2. Have Electrical Components Checked
Hire a qualified technician (like one of our Longmont pros) to inspect your electrical system for safety and efficiency.
3. Evaluate and Replace the Spa Cover
Covers can wear out over time, losing heat retention and collecting mildew. If your cover is sagging, cracking, or unusually heavy, it might be time to replace it. We carry custom-fit replacements in-store.
