pH minus 7kg
£25.95
Keep your spa or pool water balanced with pH minus. This larger 7kg container lowers high pH levels and helps maintain clear, comfortable water for relaxing hot tub sessions.
- Product description
- Specifications
Keeping your hot tub or swim spa water balanced is essential for comfort, clarity and effective water treatment. Our pH decreaser (7kg tub of granules) is designed to safely reduce pH levels when test results show that water has become too alkaline.
If the pH level rises above the recommended range of 7.2 to 7.6, it can lead to cloudy or hazy water, scaling on surfaces, reduced sanitiser performance and potential sensitive skin or eye irritation. These issues can make your spa less enjoyable and harder to maintain.
Using pH minus helps bring the water back into balance, creating comfortable conditions for bathers while allowing sanitisers such as chlorine to work effectively. Balanced water also helps protect pumps, heaters and other important spa components.
This 7kg container provides a long-lasting supply, often enough for up to a year depending on usage. Regular testing with 3 way test strips helps you quickly identify when pH adjustments are needed to maintain ideal water conditions.
