PH002 digital PH tester is an upgraded version, the Auto Calibration Button is applied for easy operation.
It is the most important to test the water PH before keeping the gold or koi fishes in the pond. Once I brushed a layer of hydro sealant to my pond, afterwards I washed the pond many times and kept the water in the pond for a week then drained out. Before I transferred the gold and koi fishes into the pond, I even added half pond with the old water which the fishes were living. Unfortunately all fishes died overnight. The PH can not be guessed, it has to be tested. The images showed the PH testing results after I repaired my fish ponds.
