Review on 🐠 JNW Direct 9 in 1 Aquarium Test Strips for Fish Tank - 100 Strip Pack | Accurate Freshwater and Saltwater Water Testing | Test Hardness, Carbonate, Nitrate, Nitrite, pH & More by Crystal Forrest

I have used two brands of 7-in-1 test strips and found them to be the most accurate compared to their lesser API Liquid Master test kit counterparts. The pH, chlorine, nitrate and nitrite readings were so "accurate" that I rely on them on a daily basis. found them somewhat inconsistent from package to package. I'm glad I found these from JNW, which mimic what Stript Health offers but are pleasantly more economical, especially with the 100 and 150 strips offered by JNW. is somewhat subjective, but with the right lighting and a plastic-protected chart on the bottle, it becomes easy to analyze and detect changes in biology long before dangerous stages occur. These strips and single cards are salt and fresh water compatible and I recommend and will continue to use them as a fish farming staple.
