## Long description

Acrylmed CALCID MINUS is a professional-grade liquid chemical solution specifically formulated to reduce the pH level of swimming pool water. Maintaining an optimal pH balance is critical for ensuring the effectiveness of disinfection processes and providing a comfortable swimming environment. This concentrated 1-litre formula is designed for precise dosing, helping to maintain crystal-clear and safe water quality in both private residential pools and public swimming facilities. By stabilizing the pH levels, this product also assists in preventing the formation of scale deposits on pool surfaces and equipment, thereby enhancing the overall performance of other water treatment chemicals.
Advantages
The primary benefit of using Acrylmed CALCID MINUS is its highly concentrated liquid form, which allows for rapid dissolution and immediate action within the pool water. Unlike granular alternatives, this liquid agent minimizes the risk of undissolved particles settling on the pool floor, ensuring a more uniform distribution. Regular application of this pH reducer creates a stable chemical environment that protects pool infrastructure from corrosion and scale buildup. Furthermore, by keeping the pH within the recommended range, it significantly improves the efficacy of chlorine and other sanitizers, leading to cleaner water and reduced chemical consumption over time.
Suitable for
Private residential swimming pools
Public swimming facilities and spas
Hot tubs and whirlpools requiring pH adjustment
Pools equipped with automatic dosing systems
When it may not be suitable
This product is not intended for use in pools where the pH level is already within the recommended range of 7.0 to 7.4, as further reduction may lead to acidic water that can damage pool liners, metal components, and cause skin irritation. It is also not suitable for pools that utilize non-compatible water treatment systems or for applications involving non-aquatic water storage.
Key specifications
Volume: 1 litre
Form: Liquid concentrate
Function: pH reduction
Compatibility: Suitable for private and public pools
How to use
Before applying Acrylmed CALCID MINUS, test the current pH level of the pool water using a reliable testing kit. If the pH value exceeds 7.4, calculate the required dosage based on the pool volume and the manufacturer's guidelines. Slowly pour the measured amount of the liquid into the pool water, preferably near the water inlet or return jets, while the filtration system is running to ensure thorough mixing. Wait for the water to circulate completely before re-testing the pH level. Adjustments should be made gradually to avoid drastic fluctuations in water chemistry.
What to consider before purchase
Check your current pool water pH level to confirm the need for a reducer
Ensure compatibility with your existing pool filtration and dosing equipment
Store the product in a cool, dry, and well-ventilated area away from direct sunlight
Always wear protective gloves and eyewear when handling pool chemicals
Usage recommendations
Regular monitoring of water chemistry is essential for pool maintenance. It is recommended to test the pH level at least twice a week and after heavy rainfall or high bather load to ensure consistent water quality and safety.
