Value for Money02GenericClub Pro | 2 Pack | (1) pH Up 750g | (1) pH Down 950g | for Hot Tub & Spa | Use with Sanitizer Such As Bromine & Chlorine | Water Treatment Chemicals | Hot Tub Accessories
Free ShippingMain highlights- pH Regulation: pH Down serves as an effective agent to lower the pH levels in hot tub water. An optimal pH range between 7.2 and 7.6 is crucial for bather comfort and to protect the tub's equipment. This compound helps in achieving and maintaining this balance, ensuring a comfortable and safe environment for users while preventing damage to the tub and its components.
- Prevents pH Fluctuations: Regular use of pH Up helps prevent sudden fluctuations in pH levels. Factors such as rainwater, bather load, and the addition of other chemicals can alter the pH. However, incorporating pH Plus as needed helps maintain a stable pH level, reducing the need for frequent adjustments and ensuring consistent water quality.
- Prevention of Skin and Eye Irritation: Balanced pH levels are integral to prevent skin irritation and eye discomfort among hot tub users. When the pH is too high, it can cause skin dryness, while low pH levels can result in skin irritation. pH Down helps maintain the pH within the ideal range, reducing the risk of such discomforts and ensuring an enjoyable experience for bathers.
- Equipment Protection: Unbalanced pH levels, especially low pH, can cause significant damage to hot tub equipment. Low pH levels can corrode metal components, such as heaters, pumps, and jets, leading to costly repairs or replacements. Incorporating pH Plus into the water maintenance routine helps prevent this corrosion, prolonging the lifespan of crucial hot tub components and reducing maintenance costs.
- Enhanced Sanitizer Efficiency: Maintaining proper pH levels significantly enhances the effectiveness of sanitizers, such as chlorine or bromine, used in hot tubs. When the pH is within the recommended range, these sanitizing agents perform optimally, ensuring bacteria and contaminants are efficiently eradicated from the water, promoting a clean and hygienic environment.
