A basic tester for measuring Cl / pH values in pool water. First, measure the pool water values and, if they are not within the normal range (pH 6.9-7.4; Cl 0.3 - 0.7), adjust the pool water using pool chemicals. First adjust the pH value (pH+ or pH-) and then adjust the chlorine level (only increase it - if the chlorine level is too high, do not reduce it; it will drop on its own in a few days). Chlorine should be added only after pH regulation because the effectiveness of chlorine outside the recommended pH range drops rapidly. The drop tester includes a set for measuring pH and a set for measuring the chlorine level in water. The pool tester is an indispensable helper if you want to ensure the proper functioning of the processes taking place in pool water. During the season, testing should be carried out every 7 - 14 days depending on pool usage, or whenever you suspect that water quality is deteriorating.
