Owning a hot tub in North Carolina means enjoying year-round relaxation, hydrotherapy, and family fun – but only if your spa is well-maintained. At AquaVision Pool & Spa, we’ve seen how small hot tub maintenance missteps can lead to big problems, from cloudy water to equipment failure.
Whether you’re a new spa owner or a seasoned soaker, this guide will help you avoid the most common hot tub maintenance mistakes we see throughout Greensboro, High Point, and beyond.
Let’s dive into the 10 most common hot tub maintenance mistakes, and how to avoid them, so your investment remains clean, safe, and soothing for years to come.
1. Neglecting Regular Water Testing
Water testing is the foundation of proper hot tub maintenance.
Failing to check your water chemistry can result in murky water, skin irritation, and long-term damage to your hot tub’s components. The North Carolina climate, with its fluctuating humidity and temperatures, can make your spa water chemistry even more volatile.
Make it a habit to test your water 2–4 times per week using test strips or a digital tester. You’re checking for pH levels, alkalinity, sanitizer levels (like chlorine or bromine), and calcium hardness. At AquaVision, we also recommend bringing a water sample to one of our showrooms for a free professional water analysis, especially if you’re unsure about your readings.
Pro Tip: AquaVision’s Spa Sense™ System takes the guesswork out of water care with personalized solutions.
2. Infrequent Water Replacement
If your water looks clean, that doesn’t mean it is.
Many hot tub owners assume that if the water looks fine, it’s okay to leave it. In reality, the water becomes saturated with dissolved solids from sweat, lotions, and chemicals over time, reducing its effectiveness and clarity.
We recommend draining and refilling your hot tub every three to four months, depending on usage. This keeps your water fresh and your chemical usage low, saving you time and money in the long run. Always flush the plumbing lines during this process to prevent biofilm buildup.
Signs it’s time to change your water:
- Foam buildup that won’t go away
- Strong chemical odor
- Cloudy water that resists clarification
3. Overlooking Filter Maintenance
Your filter is the unsung hero of water clarity.
Hot tub filters trap contaminants like dirt, oils, and hair, but if you don’t clean them, they become breeding grounds for bacteria. We often see customers come in with cloudy water issues that trace back to a clogged or neglected filter.
To maintain top performance:
- Rinse your filter weekly with a garden hose.
- Use a filter cleaner solution and soak it monthly.
- Replace your filter every 12–18 months, depending on usage.

4. Mismanaging Chemical Usage
Too much or too little can both spell disaster.
Over-chlorinating or under-sanitizing are two extremes that lead to problems like corrosion, skin irritation, and algae growth. More isn’t better, balance is key.
When adding chemicals:
- Always read the labels.
- Add one chemical at a time and wait 30 minutes between additions.
- Run your jets to circulate the water.
Less experienced owners often “shock and guess,” dumping in chemicals randomly. Instead, use a reliable water care system like SpaGuard or ask our team for a custom plan based on your spa model and water usage.
5. Ignoring pH and Alkalinity Levels
Don’t underestimate the power of pH balance.
Unbalanced water isn’t just uncomfortable – it can damage your spa’s plumbing and equipment. The ideal pH level is between 7.2 and 7.6, while total alkalinity should be between 80 and 120 ppm.
Low pH? Your water becomes acidic, which can corrode metal parts and irritate skin. High pH? It leads to scaling and cloudy water.
To fix this:
- Use pH increaser or pH decreaser as needed.
- Always adjust alkalinity before pH.
- Test again after 30–60 minutes.

6. Skipping Routine Inspections
It’s not just about what you can see – it’s what you don’t.
Routine inspections can prevent small problems from becoming expensive repairs. Once a month, take a few minutes to visually check:
- Pump seals for leaks
- Jets for obstructions
- Cover for tears or waterlogging
- Control panel for error messages
If you’re not sure what you’re looking for, AquaVision’s certified technicians can perform a full diagnostic inspection – especially helpful before summer or winter.
7. Not Cleaning the Hot Tub Cover
Your cover does more than just keep out leaves.
Hot tub covers trap heat, reduce evaporation, and keep debris out. But if you neglect them, they can become heavy with water, develop mildew, and start to degrade – eventually leaching grime into your spa.
Clean your cover every 2–4 weeks using mild soap and water. Rinse thoroughly and apply a UV protectant spray to prevent cracking and fading in the North Carolina sun.
Bonus: AquaVision carries Covana automated covers, which offer weather resistance and convenience in one sleek system.
8. Running the Hot Tub with Low Water Levels
Your pump can’t pump if there’s nothing to move.
One of the fastest ways to damage your hot tub is running it with low water levels. This forces air into the circulation system, risking pump burnout and heater damage.
Check your water level weekly, especially after multiple users or splashing. Water should be above the highest jet. If you notice rapid water loss, check for leaks or contact AquaVision’s service team for fast repairs.
9. Failing to Address Foam and Scum Buildup
That foam party wasn’t invited.
Foam is usually caused by body oils, lotions, detergents from swimsuits, and poor water chemistry. Scum rings often result from organic buildup around the waterline.
How to fix it:
- Use a foam reducer as a temporary fix.
- Add an enzymatic cleaner to break down organics.
- Rinse off before entering the hot tub.
- Avoid using regular laundry detergent on swimwear.
Regularly cleaning your filters and adjusting water balance can prevent most foam issues altogether.
10. Disregarding Seasonal Maintenance
North Carolina’s seasons demand preparation.

Winter freezes and summer heatwaves both affect your hot tub’s performance and longevity. Don’t get caught off guard.
For winter:
- Insulate your pipes if you won’t be using the tub.
- Keep water circulating to prevent freezing.
- Use a weather-resistant cover.
For summer:
- Check sanitizer levels more frequently due to increased UV exposure.
- Leave the cover partially open after use to prevent overheating.
- Maintain proper ventilation in enclosed areas.

How To Create a Hot Tub Maintenance Schedule That Works
One of the best ways to avoid all the mistakes we’ve discussed is to set a consistent hot tub maintenance schedule. This ensures you’re proactively addressing potential issues rather than reacting to problems once they’ve already developed.
Weekly Tasks:
- Test pH, alkalinity, and sanitizer levels.
- Rinse the hot tub filter with a garden hose.
- Add balancing chemicals if needed.
- Wipe the waterline to prevent scum buildup.
Monthly Tasks:
- Deep clean the filter with a dedicated filter cleaner.
- Inspect jets, plumbing, and pump performance.
- Check for any signs of foam, algae, or unusual odors.
Quarterly Tasks:
- Drain and refill the hot tub.
- Flush plumbing lines to remove biofilm and bacteria.
- Deep clean the shell and cover with a non-abrasive cleaner.
Keeping a simple printed or digital checklist can help make this process foolproof and more manageable.
How Proper Hot Tub Maintenance Saves Energy
A clean, balanced, and well-insulated hot tub runs more efficiently – helping you cut down on energy bills while extending the life of your components.
Here’s how:
- Clean filters reduce strain on your pump and heater.
- A tight-fitting cover locks in heat, reducing heating time.
- Well-balanced water chemistry prevents scaling and buildup that reduce heater performance.
Pro Tip: A dirty or waterlogged cover can cause up to 30% of heat loss. Replacing it with an insulated or automated Covana cover can pay off fast.
Common Signs of Trouble to Watch For
Spotting early warning signs can help you avoid expensive service calls and downtime. Call AquaVision if you notice:
- Foam that keeps returning after treatment
- Strong chemical or acid smells
- Jets not working properly
- Heater taking longer to warm water
- Persistent algae or cloudy water
- Waterline scum buildup
If you’re unsure, our certified service technicians offer full diagnostic checks for hot tubs across Greensboro, High Point, and surrounding areas.
