## Long description

Marimex pH- is a professional chemical agent designed to effectively reduce the pH value of water in swimming pools. Maintaining an optimal pH level between 7.0 and 7.4 is essential for the proper functioning of disinfection products and for ensuring comfortable bathing conditions. This 2.7 kg granular preparation is easy to dose and helps prevent water clouding, scale formation, and skin or eye irritation.
Advantages
The primary benefit of using Marimex pH- is its ability to stabilize pool water chemistry, which significantly enhances the efficiency of chlorine and other disinfectants. By keeping the pH within the recommended range, you prevent the water from becoming too alkaline, which often leads to cloudy water and the buildup of mineral deposits on pool walls and filtration systems. This granular formula dissolves quickly and is gentle on pool equipment, ensuring a longer lifespan for your filtration components and accessories while providing a safer and more pleasant swimming environment for all users.
Suitable for
Private outdoor swimming pools
Indoor swimming pools
Hot tubs and whirlpools
Maintaining water balance for effective disinfection
When it may not be suitable
This product is not suitable for pools where the pH level is already below 7.0, as further reduction could lead to acidic water that may corrode metal components and damage pool liners. It should also not be used in water systems that do not require pH adjustment or in environments where specific chemical compatibility is restricted by the manufacturer.
Key specifications
Weight: 2.7 kg
Form: Granular
Function: pH reduction
Optimal pH range maintenance: 7.0–7.4
How to use
Before applying the product, measure the current pH level of your pool water using a testing kit. If the value exceeds 7.4, calculate the required amount of Marimex pH- based on the volume of your pool. Dissolve the measured amount of granules in a separate plastic container filled with water, then pour the solution evenly along the edge of the pool while the filtration system is running to ensure thorough mixing. Wait for at least one full filtration cycle before re-testing the water to verify the results.
What to consider before purchase
Check your current pool water pH level with a tester
Calculate the total volume of your pool in cubic meters
Ensure you have appropriate protective gloves and eyewear
Store in a cool, dry place away from direct sunlight
Usage recommendations
Always add the chemical to water, never add water to the chemical. Store the container tightly closed in a dry, well-ventilated area out of reach of children and pets.
