5-in-1 Test Strips, tests for 5 important parameters in order to keep swimming pool water in balance.
Every second week
Or every second day to determine the correct chemicals to correct the water balance when the water-colour is not crystal clear
In what order should test swimming pool water?
With today's modern test strips, all parameters are tested in one go, but we suggest that you focus on adjustment of only one parameter at a time to determine the chemical to be added.
Total Alkalinity (TA)
Total alkalinity refers to how much alkaline is in the water, but you can't fully know the importance of total alkalinity without referring to pH because the two influence one another. Low alkaline water leads to low pH and high alkaline water leads to high pH. A pool should have a total alkalinity level of 100 ppm.
pH Levels
Keeping your pH levels within the proper range is important for both swimmer comfort and keeping your equipment and finish in good condition. pH refers to the acidity or baseness of your pool water. A properly balanced pool has a pH level is in the range of 7.2 to 7.8
The scale has levels from 0 to 14. 0 to 7 reflects a low or acidic pH, and 8 to 14 means the pool has a base pH level. Low pH readings mean your chlorine will dissipate quickly, whereas high pH levels make chlorine inactive. This means that the money you're spending on chlorine is, unfortunately, wasted.
Calcium Hardness (TH)
The right amount of calcium in pool water is crucial. Too little and your pool's surface can begin "chalking" and erode. Too much and your water could become murky, scale formations could appear, and stains might begin to form. 200 to 400 ppm is the general range for calcium hardness levels.
Free Chlorine (FC) & Total Chlorine (TC)
The most efficient way to sanitise your pool and keep swimmers safe is with chlorine. Bacteria from swimmers' bodies, debris or animals can enter and contaminate pool water. All of these are reasons for adding chlorine to your pool.
The ideal level of Free Chlorine is 1 to 3 ppm (parts per million). Free Chlorine (FC) is the available chlorine that kills bacteria and keep water healthy. As soon as FC combines with bacteria or other nasty stuff it is called "Combined Chlorine" or so-called Chloromines.
We want the "Combined Chlorine" to be less than 0,2ppm or Zero.
These test strips do not measure the level of "Combined Chlorine", but it can be calculated with the following formula:
Combined Chlorine = Total Chlorine - Free Chlorine
