Acrylmed CALCID MINUS pH Lowering Liquid for Swimming Pools 2 Litres

Acrylmed CALCID MINUS is a professional liquid chemical agent specifically formulated to reduce the pH level of swimming pool water. Maintaining an optimal pH balance, typically between 7.0 and 7.4, is critical for the effectiveness of disinfection chemicals and the overall comfort of swimmers. This 2-litre concentrated solution provides a reliable method for managing water chemistry, preventing common issues such as water cloudiness, skin irritation, and the buildup of calcium scale on pool surfaces and equipment.

Advantages

The primary benefit of using Acrylmed CALCID MINUS is its high efficiency in stabilizing pool water chemistry. By effectively lowering pH levels, it ensures that chlorine-based disinfectants work at their maximum potential, which is essential for maintaining a hygienic swimming environment. The liquid formula is designed for rapid dissolution and easy dosing, allowing for precise adjustments without the risk of undissolved particles settling on the pool floor. Regular application helps protect pool infrastructure from scale deposits and ensures the water remains clear and inviting for all users.

Suitable for

• Private residential swimming pools
• Public swimming facilities
• Hot tubs and spas requiring pH adjustment
• Pools using chlorine-based disinfection 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 or is too low, as further reduction could lead to acidic water that may corrode metal components and damage pool liners. It should not be mixed directly with other concentrated pool chemicals in the same container.

Key specifications

• Volume: 2 litres
• Form: Liquid
• Function: pH reduction
• Application: Swimming pool water treatment

How to use

Before application, test the current pH level of the pool water using a reliable test kit. To lower the pH by 0.1 units, typically add approximately 100 ml of the product per 10 cubic meters of water, though exact requirements may vary based on total alkalinity. Dilute the required amount of the liquid in a plastic bucket with water before pouring it slowly into the pool, preferably near the water inlet or around the perimeter while the filtration system is running to ensure even distribution. Wait for the water to circulate thoroughly before re-testing the pH levels.

What to consider before purchase

• Check your current water pH and total alkalinity levels
• Ensure compatibility with your existing pool filtration system
• Calculate the required dosage based on your pool volume
• Store in a cool, dry, and well-ventilated area away from children

Usage recommendations

Always wear protective gloves and eyewear when handling pool chemicals. Avoid direct contact with skin and eyes. If the pH level remains high after treatment, repeat the process in small increments rather than adding a large dose at once.
