## Long description

Acrylmed CALCID MINUS is a professional liquid chemical agent specifically formulated to effectively reduce and stabilize the pH level of swimming pool water. Maintaining an optimal pH balance, typically between 7.0 and 7.4, is critical for ensuring water clarity, preventing skin and eye irritation, and maximizing the efficiency of chlorine-based disinfectants. This 0.5-litre concentrated solution is designed for precise dosing, making it a reliable choice for both private and public pool maintenance.
Advantages
The primary benefit of using this liquid pH reducer is its rapid solubility and ease of application compared to granular alternatives. By quickly integrating into the water circulation system, it prevents localized cloudiness and ensures uniform chemical distribution. Regular use of this product protects pool equipment from scale buildup and corrosion, which are common consequences of high pH levels. Furthermore, it creates a more comfortable swimming environment by ensuring that the water remains gentle on the skin and eyes, while simultaneously allowing secondary sanitizers to work at their peak performance levels.
Suitable for
Private outdoor and indoor swimming pools
Hot tubs and whirlpools requiring pH adjustment
Pools using chlorine or bromine disinfection systems
Regular water maintenance routines
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 damages pool liners, metal components, and equipment. It should not be used in conjunction with incompatible chemicals without proper water testing.
Key specifications
Volume: 0.5 litres
Form: Liquid concentrate
Function: pH reduction
Compatibility: Suitable for most standard pool filtration systems
How to use
Before application, test the current pH level of the pool water using a reliable test kit. If the pH is above 7.4, calculate the required amount of Acrylmed CALCID MINUS based on the pool volume and the manufacturer's dosage guidelines. Dilute the measured amount of the liquid in a plastic container with water before pouring it slowly into the pool, preferably near the water inlet or around the perimeter while the filtration pump is running. Allow the water to circulate for several hours before performing a follow-up test to ensure the desired pH level has been achieved.
What to consider before purchase
Verify the current pH level of your pool water before application
Ensure the product is stored in a cool, dry place away from direct sunlight
Keep out of reach of children and pets
Use protective gloves and eyewear during handling
Usage recommendations
Always add the chemical to water, never add water to the chemical. Perform regular water testing at least once a week to maintain stable conditions and prevent large fluctuations in water chemistry.
