Test Tablets DPD No. 4 O2 - 10 pcs

Product detailed description

The tester is used to test the oxygen and the pH of the pool water. In order to keep your pool water crystal clear, its use is absolutely necessary. First, measure the pool water values ​​and if they are not standard (pH 6.9-7.4; 2 & nbsp; 3.0-8.0 mg/l & nbsp;), adjust the pool water using pool chemistry. First, adjust the pH (PH+ or PH-) value and subsequently adjust the Oxygen value (only increase-if the value & nbsp; oxygen is too high, do not reduce it, drop it in a few days). Oxygen is applied only after the pH regulation because the efficiency & nbsp; oxygen outside the recommended pH values ​​decreases rapidly
