Keeping your hot tub water clean is essential for both user health and the longevity of the equipment. Without regular maintenance, impurities accumulate, leading to clogged filters and potential damage. Additionally, improper use of chemicals can degrade water quality and cause health risks. To ensure a safe and enjoyable experience, a consistent maintenance routine is necessary. The frequency of maintenance depends on usage, the number of users, and local water conditions.

JOYEE has developed this water maintenance guide to help users maintain high water quality and extend the life of their hot tubs.

1. Essential Aspects of Water Maintenance

Proper hot tub water management includes three key elements:

Filtration System: Removes dirt and debris to keep water clear.

pH Balance: Maintains a stable pH between 7.2 and 7.6 to prevent scaling and corrosion.

Disinfection: Regularly sanitizing the water eliminates bacteria and other harmful microorganisms.

2. Preventing Water Contamination

To keep the water clean, an appropriate amount of disinfectant must be used. JOYEE recommends maintaining the following water quality levels:

Chlorine: 3 - 5 ppm

pH: 7.2 - 7.6

Calcium Hardness: 250 - 500 ppm

Total Alkalinity: 125 - 150 ppm

Important Maintenance Tips:

①Always run the circulation system when adding chemicals.

②Inspect and clean the filter basket every four weeks to ensure proper filtration.

③Wash the filter cartridge or filter bag every four weeks to remove debris.

④Change the water nearly every three months to maintain cleanliness.

3. Filtration System Care

To maintain an efficient filtration system, regular inspection, cleaning, and replacement of filter cartridges or bags are necessary. Clean filters ensure proper water flow and keep the hydrotherapy system functioning efficiently.

Important Notes:

Cleaning frequency depends on usage—more frequent use requires more frequent cleaning.

How to Replace the Filter Cartridge:

①Turn off the power and remove the filter cover.

②Remove the used filter cartridge.

③Install a clean replacement.

④Secure the filter cover back in place.

4. Safe Handling of Chemicals

When using chemical products for water treatment, it is essential to follow product instructions and observe safety precautions to minimize health risks and prevent equipment damage.

˃ Assign a designated person to handle chemicals and ensure they are stored out of reach of children.

˃ Keep chemical containers sealed and store them in a dry, well-ventilated area.

˃ Avoid inhaling chemical fumes and prevent contact with eyes, nose, and mouth. Wash hands thoroughly after handling.

˃ In case of accidental inhalation, follow emergency procedures listed on the product label.

˃ Do not smoke while handling chemicals, as many are flammable.

˃ Never add chemicals directly to hot tub components; store them in a clean, dry, and ventilated area.

˃ Add different chemicals separately—allow one to fully dissolve before adding another to prevent adverse reactions.
˃ Do not add any chemical products to the water while the people in the hot tub to avoid causing irritation to users.

5. pH Adjustment Methods

Recommended pH Range: 7.2 - 7.6

pH measures the acidity and alkalinity of water. A pH value below 7.0 indicates acidic water, while a value above 7.0 indicates alkaline water.

Why Is pH Balance Important?

Low pH (<7.2): Causes rapid disinfectant depletion, increases corrosion of hot tub components, and may cause skin irritation.

High pH (>7.6): Reduces disinfectant effectiveness, causes cloudy water, promotes scale buildup, and may clog the filtration system.

Steps to Adjust pH Levels:

If the pH is too high, add an appropriate amount of pH Decreaser, then wait 2 hours before retesting.

If the pH is too low, add an appropriate amount of pH Increaser, then wait 2 hours before retesting.

6. Water Disinfection Management

Regular disinfection is essential to prevent the growth of bacteria, algae, and microorganisms in the hot tub. However, excessive use of disinfectants may cause skin and eye irritation.

Chlorine tablets are an effective disinfectant for hot tub water. They are typically placed in the filtration system, where they dissolve slowly to provide continuous sanitation. It is recommended to check chlorine levels daily using a chlorine test kit, maintaining an ideal range of 2.2 - 3.3 ppm.

7. Specialized Hot Tub Maintenance Chemicals

In addition to standard pH adjusters and disinfectants, specialized chemical products can further enhance water quality stability:

Scale Inhibitor: Prevents calcium salt deposits, especially in hard water conditions. Recommended for weekly use and during water changes.

Algaecide: Suppresses algae growth. Recommended for weekly use and during water changes.

Degreaser: Removes oils and contaminants from the hot tub surface. Before refilling the tub, apply degreaser to a sponge, scrub the stained areas, and rinse thoroughly with clean water to maintain a smooth and clean tub interior.

8. Ozone Treatment System

Ozone is an advanced and highly effective water purification method that leaves no chemical residues and has no strong odor. Its oxidizing properties effectively break down organic matter, reducing the need for chlorine or bromine.

The ozone generator operates automatically when the filtration system is running. It extracts oxygen from the air, converts it into ozone, and releases it into the water through jets for disinfection. While ozone treatment significantly enhances water cleanliness, it does not completely replace chlorine or bromine and should be used as a supplementary sanitation method.

Conclusion

Following a proper water quality management plan not only keeps hot tub water clean and clear but also extends the lifespan of the equipment. Regular pH testing, disinfectant use, filtration system cleaning, and specialized chemical treatments help prevent water contamination and equipment damage, ensuring a safe and enjoyable soaking experience.

JOYEE's Water Management Guide is designed to help users effortlessly maintain pristine water conditions. By adhering to these best practices, your hot tub will remain in peak condition, providing long-lasting enjoyment for you and your family.
