Hey All - I wanted to pick up a tester for chlorine to check the carbon on my RODI unit. Right now i'm between the Hanna standard total chlorine and the ULR.
Standard Range - 0 to 3.5ppm, 0.01ppm resolution
Ultra Low Range - 0 to 500ppb (or 0.5ppm), 1ppb resolution
Based on this article from the Hanna website i'm leaning towards the ULR;
"Chlorine is a strong oxidant and can be lethal to most fish at level between 0.1-0.3 ppm. Although is its best to maintain levels below 0.001 to 0.003 ppm as health issues can arise in aquatic systems."
Is ULR the way to go or are there better options i should consider?
