Owning a hot tub is a great way to relax and unwind, but it requires proper care and maintenance to keep the water clean and safe. Whether you’re a new hot tub owner or just looking to refresh your knowledge, this guide will walk you through the essential steps for maintaining your hot tub and ensuring crystal-clear water all year round.
Why Hot Tub Maintenance is Important
A well-maintained hot tub not only looks better, but it’s also safer to use. Hot tubs that aren’t regularly cleaned can become breeding grounds for bacteria, which can lead to skin irritations, rashes, and other health issues. Keeping the water chemistry balanced also helps prevent equipment damage and prolongs the life of your hot tub.
Daily Hot Tub Maintenance
Here are some simple daily tasks to keep your hot tub in top shape:
- Check Water Levels: Ensure the water level is high enough to cover the jets but not too high to cause overflow. If the water level is low, top it off with fresh water.
- Run the Jets: Turn on the jets for about 10-15 minutes daily. This circulates the water and ensures that the chemicals are distributed evenly throughout the tub.
- Test the Water Chemistry: Using a water test strip, check the water’s pH, alkalinity, and sanitizer levels. These levels should be checked daily to maintain a safe and balanced hot tub environment.
Weekly Hot Tub Maintenance
Each week, you’ll need to perform some extra maintenance tasks to keep your hot tub in top condition:
- Shock the Water: Shocking the water involves adding a large dose of sanitizer to remove organic contaminants, oils, and bacteria that accumulate over time. Use chlorine shock or non-chlorine shock depending on your tub’s sanitizer system.
- Shock dosage: Add 50g of shock per 1,000 liters of water.
- Clean the Filters: Hot tub filters can become clogged with dirt, oils, and debris. Remove the filter and rinse it under a hose to clear out any particles. For deeper cleaning, soak the filter in a solution of water and filter cleaner for several hours, then rinse it thoroughly before reinstalling.
- Wipe Down the Shell: Use a soft cloth and non-abrasive cleaner to wipe down the interior surfaces of the hot tub. This prevents biofilm buildup and keeps the shell looking shiny and clean.
Balancing Hot Tub Chemicals
Proper water chemistry is the cornerstone of hot tub maintenance. Here’s how to keep your hot tub’s chemical levels in check:
- pH Levels: Aim for a pH level of 7.2-7.8. Low pH can cause the water to become too acidic, which can corrode the hot tub’s components. High pH levels make the water cloudy and reduce sanitizer effectiveness. Use pH increaser or pH decreaser to adjust the levels as needed.
- pH increaser dosage: Add 10g per 1,000 liters to raise pH.
- pH decreaser dosage: Add 20g per 1,000 liters to lower pH.
- Alkalinity: Total alkalinity should be between 80-120 ppm. This helps prevent drastic pH swings. Use alkalinity increaser or baking soda to raise the levels if necessary.
- Alkalinity increaser dosage: Add 25g per 1,000 liters to raise alkalinity by 10 ppm.
- Sanitizer Levels: Depending on your system, you’ll need to maintain either chlorine or bromine levels. Chlorine levels should be between 1-3 ppm, while bromine should be kept at 3-5 ppm.
Monthly Hot Tub Maintenance
Once a month, it’s important to conduct a more thorough cleaning of your hot tub. This process will help ensure your water stays fresh and your equipment functions properly.
- Drain and Refill the Water: Over time, the water in your hot tub becomes saturated with chemicals, oils, and other contaminants, making it harder to maintain proper water chemistry. Draining and refilling your hot tub every 4-6 weeks ensures the water remains fresh and clean.
- Tip: Before draining the water, add a pipe cleaner or line flush product to remove any buildup in the plumbing lines.
- Deep Clean the Shell and Cover: While the tub is empty, give the entire shell a deep clean using a non-abrasive cleaner and a soft cloth. Make sure to wipe down the cover as well, as it can accumulate dust, dirt, and mildew.
- Inspect and Replace Filters: Check your filters for any signs of wear or damage. Filters typically last about a year, but they may need to be replaced sooner if they become damaged or clogged beyond cleaning.
Balancing Chemicals After Refilling
Once you’ve refilled your hot tub with fresh water, it’s important to re-balance the chemicals:
- Test the Water: Use a test strip to check the pH, alkalinity, and sanitizer levels.
- Add Sanitizer: Depending on your system, add the appropriate amount of chlorine or bromine to the water.
- Adjust pH and Alkalinity: If the pH or alkalinity levels are off, add the necessary chemicals to bring them back into the correct range.
Preventing Biofilm and Scale Build-Up
Biofilm and scale can form in your hot tub over time, especially if water chemistry isn’t properly maintained. Here’s how to prevent these issues:
- Use a Scale Inhibitor: If you have hard water, scale buildup can occur on the surface of your hot tub and in the plumbing lines. Add a scale inhibitor to the water once a month to prevent this.
- Dosage: Add 50ml per 1,000 liters of water.
- Clean the Plumbing Lines: Use a pipe cleaner product or line flush every time you drain your hot tub. This helps to remove biofilm, which can harbor bacteria and clog the plumbing.
Energy-Efficient Hot Tub Tips
Keeping your hot tub running efficiently can save you money on energy costs and prolong the life of your equipment. Here are a few energy-saving tips:
- Use a Thermal Cover: A well-insulated cover helps retain heat and prevents water evaporation. Make sure the cover fits tightly over the tub to keep the heat in.
- Lower the Temperature When Not in Use: If you’re not using the hot tub for a few days, lower the temperature by a few degrees. This reduces the amount of energy required to maintain the water temperature.
- Use a Timed Circulation Pump: Many hot tubs have a timer function that allows you to run the circulation pump for a set number of hours each day. Running the pump for 4-6 hours daily is usually sufficient to keep the water clean while reducing energy consumption.
When to Call a Professional
While most hot tub maintenance tasks can be done by the homeowner, there are a few situations where you should call a professional:
- Persistent Cloudy Water: If your water remains cloudy despite balancing the chemicals and cleaning the filters, there may be an issue with your hot tub’s plumbing or filtration system.
- Equipment Malfunction: If your hot tub’s heater, pump, or jets stop working, or if you hear unusual noises, it’s best to have a professional inspect the equipment to prevent further damage.
- Leaks: If you notice water levels dropping rapidly, there may be a leak in the plumbing lines or the hot tub shell. A professional will be able to locate and repair the leak.
Hot Tub Safety Tips
Maintaining a clean hot tub isn’t just about comfort — it’s also about safety. Follow these safety tips to ensure your hot tub remains a safe place for you and your family to relax:
- Monitor Water Temperature: Keep the water temperature below 40°C (104°F) to prevent overheating. Prolonged exposure to high temperatures can lead to dizziness, dehydration, or more serious health issues.
- Limit Soak Time: Limit soak time to 15-20 minutes at a time to avoid overheating or dehydration.
- Keep the Hot Tub Covered: When the hot tub is not in use, always keep it covered. This prevents children or pets from accidentally falling in and helps maintain water cleanliness.
Conclusion
With regular maintenance and proper chemical balancing, your hot tub will remain a relaxing and safe haven for you to enjoy year-round. By following these daily, weekly, and monthly maintenance steps, you can ensure your hot tub stays clean, comfortable, and ready for use whenever you need it.
