Review on 🐟 Efficient Molop Calibration for Optimal Aquarium Water Quality and Fish Health by Robert Moloney

I used this item to check the purity and alkalinity of the water. I did not calibrate any of the devices but used them straight out of the box. I used tap water as a baseline and every test showed that the filtered water had significantly lower ppm and higher alkalinity. 200 ppm for filtered and 700 ppm for spilled material. 9-phase filtered vs. 7-phase faucet. I just wanted to check if the filter is working.
