    Easy to use, no color matching

    I purchased this to do a fishless cycle for my pond and a container water garden. Although I could’ve used a cheaper test kit, I have a difficult time matching the colors and I wanted better accuracy and precision. When testing for free nitrite, aquarists usually think in ppm but this reads in ppb. Also, to get free nitrite ions, which is what most fish keepers measure, multiply by 3.29. Otherwise great colorimeter to let me know when the cycle is over and I can add fish.
