I notice alot of people give reads of 0.8ppm etc real accurate reading from testing Amminia and Nitrites etc but mine just come with a colour chat that has 0.5-1.0 and so on so what types are people using to get accurate results???
Hi. Many people prefer the liquid test kids over the strip types as they are reported to be more accurate. I use Aquarium pharmaceutical test kits and many others think they are the best as well.
