Review on 🐠 Qguai 9-in-1 Aquarium Water Test Kit - Essential for Freshwater, Saltwater, and Pond Tanks. Monitor Nitrate, Nitrite, pH Levels, Free Chlorine, and More to Prevent Hidden Issues! by Angie Wooten

Waste of money. The stripes are not exact and less than half of them give a full and accurate definition of the color. The image shows 4 strips taken at the same point in the tank a few minutes apart. The first states that my water has an alkalinity of 0, which means my water went from neutral to fully acidic in one day, causing me to panic and almost mess with my fish's water to try and fix the problem fix when this was not the case there. . actually a problem. Luckily I decided to try a few more and this is what I found. I've tried over 30 of them since I got them and most of them are buggy, maybe 7 of them have been accurate so far. Very disappointed, I will never buy again and do not recommend it to anyone.
