Review on 200 Aquarium Test Strips Accuracy by Andy Ucros

Well, first things first. It's just 4 in 1, they don't measure x. Second, the reagents don't stay in the pads, they all bleed no matter how careful you are. Nitrate levels are still wrong. I want the photos to be uploaded, I'll try again. These strips said I was over 100ppm, the other two brands plus the master kit showed around 6ppm. I repeated this with 75 strips, they were all far away. I also love how big the stripes are. just wish they had included a chlorine and kh test. and that they were of much better quality and accuracy. Don't waste your money and time. Rather spend a few euros more and get a better test device.
