Water balance – Spa

SpaCare - Water balance products for spas

It is really nice to be able to bathe in a clean and clear spa bath. One of the cornerstones of clean and clear bathing water is the right balance of the water. This applies to both the pH value and the alkalinity. When these two values are in balance, you will find it much easier to control your bathing water, as the disinfection works best in pH-neutral water around 7.0-7.4.

One of the problems that can often appear is cloudy water or limescale in the hot tub. With the correct pH value and an alkalinity in balance, you can avoid these problems.

It is a good idea that you already test the water when you pour it into your hot tub. Perhaps the alkalinity is out of balance and should therefore be adjusted so that the rest of the products work optimally.

  1. SpaCare No Scale
    • Brand: SpaCare
    • Applications: Spa
    • Liters, Product: 0,5 L

    SpaCare No Scale reduces the risk of calcium and metals precipitating and forming calcium or iron-based deposits in your spa.

    In Scandinavia, our drinking water often contains significant amounts of calcium (hard water) and metals such as iron and manganese.

    You can use this product both when filling the hot tub with water and on a weekly basis to maintain its effectiveness.

  2. SpaCare pH Down Granulate
    • Brand: SpaCare
    • Weight, Product (kg): 1,5 kg
    • Applications: Spa

    If the water's pH level is above 7.4, we recommend using SpaCare pH-Down Granular - this will lower the pH level.

    To maintain the balance of your bathwater, it's essential to measure the pH level regularly, preferably at least once a week. You can measure the pH level using a SmartTest or a tablet tester. We do not recommend using spa strips to measure the pH level.

    This product is one of our high-quality standard products and comes with a measuring scoop, making it easy for you to add the correct dose every time.

  3. SpaCare Alka Down
    • Brand: SpaCare
    • Weight, Product (kg): 1,5 kg
    • Applications: Spa

    SpaCare Alka Down reduces the alkalinity in your hot tub and helps you maintain the balance of your spa water.

    If alkalinity is higher than 120 mg/l, you may experience issues with locked pH values and cloudy water.

    It's important to measure and, if necessary, adjust the alkalinity during water replacement or if issues arise in maintaining a stable pH level between 7.0-7.4. Alkalinity should be within the range of 80-120 mg/l.

  4. SpaCare pH Up Granulate
    • Brand: SpaCare
    • Weight, Product (kg): 1 kg
    • Applications: Spa

    If the water's pH level is below 7.0, we recommend using SpaCare pH-Up Granular - this will raise the pH level.

    To maintain the balance of your bathwater, it's essential to measure the pH level regularly, preferably at least once a week. You can measure the pH level using a SmartTest or a tablet tester. We do not recommend using spa strips to measure the pH level.

    This product is one of our high-quality standard products and comes with a measuring scoop, making it easy for you to add the correct dose every time.

pH Value and Water Balance in Spas, Hot Tubs, Jacuzzis, and Wilderness Baths

pH value and water balance are crucial factors to ensure a safe and comfortable environment in spas and hot tubs. They play a significant role in water quality and can affect both the health of users and the lifespan of spa and hot tub equipment. Here is a detailed overview:

pH Value

  • Definition: The pH value is a measure of how acidic or basic the water is on a scale from 0 to 14, where 7 is neutral. Water with a pH value below 7 is considered acidic, while water with a pH value above 7 is basic (alkaline).
  • Importance for Spa and Hot Tub: In spas and hot tubs, it is typically recommended to maintain the pH value between 7.0 and 7.4. This balance ensures optimal comfort for the users and effective use of disinfectants to keep the water clean.
  • Consequences of Imbalance: Incorrect pH value can lead to irritation of skin and eyes, damage to spa equipment, and ineffective disinfection. Too low pH (too acidic) can corrode metal parts, and too high pH (too basic) can cause lime deposits and cloudy water.

Water Balance

  • Definition: Water balance refers to the relationship between different chemical components in the water, including pH value, total alkalinity (TA), and calcium hardness (CH).
  • Total Alkalinity (TA): Alkalinity acts as a buffer for the pH value, helping to stabilize it against large fluctuations. The ideal TA for spas and hot tubs typically lies between 80-120 ppm (parts per million).
  • Calcium Hardness (CH): Indicates the amount of dissolved calcium and magnesium in the water. Too low CH can lead to corrosion of metal parts, while too high CH can lead to lime deposits. Ideal CH levels for spas and hot tubs often lie between 150-250 ppm.

Maintenance

To maintain optimal water balance and pH value, it is important to regularly test the water and adjust with chemicals as necessary. This may include pH increasers or decreasers, alkalinity increasers, and calcium hardness increasers. Additionally, regular draining and refilling of the spa or hot tub is necessary to remove accumulated chemicals and contaminants.

Maintaining the correct pH value and water balance is not only important for the comfort and safety of users but also to minimize maintenance costs and extend the lifespan of spa and hot tub equipment.
