Astralpool Test Strips 3 in 1
Test strips allow for quick and easy monitoring of the basic chemical treatment parameters of pool water. The strips change color depending on the level of free chlorine, alkalinity, and pH in the water.
Always keep the strip container tightly closed and store it in a cool, dry place. The package contains 50 test strips.
If the free chlorine level is lower than 0.5, additional chlorine should be dosed into the pool.
The pH value of water indicates the degree of acidity or alkalinity of a chemical substance. The acidity or alkalinity of aqueous solutions is expressed by the pH value. In practice, it is enough to know that pH ranges from 1 to 14. pH = 7 is a perfectly neutral solution. Values lower than 7 indicate increasing acidity, while values higher than 7 indicate alkalinity. The ideal range for pools is 7.2 - 7.6. A pH higher than 7.6 leads to the formation of various mineral cloudiness, limescale, and other deposits. A pH lower than 7.2 causes corrosion of metal surfaces. The pH value affects the solubility and effectiveness of the disinfecting products used.
The alkalinity of pool water should be in the range of 100 - 175 mg / l (g / m3) CaCO3. If the alkalinity is lower than 100 mg / l (g / m3) CaCO3, use CTX-21 to increase it. If the alkalinity is higher than 175 mg / l (g / m3 ) CaCO3, part of the pool water must be drained and replaced with water with low alkalinity.
