PineSong Posted August 13, 2021 Share Posted August 13, 2021 My new co-op test strips show my KH as only 40, in both my main tank almost no water changes) and the QT tank daily water changes 25% and in a jug of Primed tapwater that is @ 12 hours old. This is puzzling to me because I'm used to API strips saying my KH is high--my memory says it was usually 180 and the only photo I found showed at least 120 if not 180. I guess I'll have to buy another set of API strips and compare them side by side to know for sure, but if it is really only KH 40, should I do anything to change it? Then..... I tried to look at the city water quality report for answers, but it doesn't list KH in any form I recognize. And to add to my confusion, its values for GH seem at odds with everything I know about my water. I live in a limestone region with hard water as identifiably by looking at glasses, coffee pots, fish tank water lines, etc. My GH has always been the highest color on API and on Co-Op test strips, but according to the city report GH in ppm (as CaCO3) averages only 128. According to another site (that sells water softeners!), my city averages 218ppm. Basically I want to know if my water dangerously low in KH, whether it is hard enough for livebearers to breed and whether it has enough calcium in it for my mystery snail. Per the city water report calcium is 46ppm. Any explanations/feedback welcome. And in case it matters, the rest of my parameters are: Nitrate: 10 Nitrite: 0 pH: 7.2 Link to comment Share on other sites More sharing options...
