There are some chemicals to be used for the pool water to be healthy. These chemicals must be added to the pool after certain measurements are made. The pH, chlorine and alkalinity values of the pool must be controlled regularly.

Poolline 3 function test stick is a measurement set of free chlorine, pH and alkalinity when the daily chlorine level must be controlled manually. Free chlorine levels are measured between 0,5-10 ppm. By alkalinity,  we mean the carbonate, bicarbonate and hydroxide that is found in dissiolved form in water. By the test kit, you can see if the alkalinity vales are between 80-120 ppm or not.
