How do you use pH minus?
Pool products need to be dosed correctly to balance the water. The CTX-10 pH- has a dosage of 150 g/10 m³ to lower the pH by 0.2. For a pool of 50 m³, 750 g must therefore be added to lower the pH by 0.2. When more than 0.2 pH needs to be reduced, we recommend doing this in steps of 0.2 pH with an interval of 2 hours per dose. Dissolve the powder in lukewarm or warm water and then add it around the pool.
Safety instructions
All pool products should be weighed before being added. NEVER add when there are bathers present. First adjust the pH to 7.2 before chlorine is added. Always close the plastic bucket properly and store it in a dry and safe place.
