Review on 📈 High Accuracy Digital pH Meter with ATC Tester - 3 in 1 Pen Type for Water, Wine, Spas, Aquariums - 0.01 pH Resolution, TDS & Temp Measurement by Melvin Goerge

This reader jumps all over the place. 6.2ph to 8ph is a big difference for Pisces and can mean life or death for some species. I had a pH issue in my tank and bought this to avoid using a drop kit. It gives inaccurate readings everywhere. I expected the readings to remain stable since it was advertised for aquariums. Not correct! Do not buy for aquariums!***UPDATE***The company contacted me after my review. They tried to bribe me to remove my review. I reject this. My feedback as a fish farmer is very important to warn other fish farmers not to use this product especially as it can kill fish. And the fact that it is advertised as an aquarium PH reader is very worrying!
