We do not see anything on the Cutrine Pus Algaecide label that says it is unsafe for carp or anything regarding water hardness. It does mention that trout could be harmed if the water is too soft or acidic. There are a few different ways to go about testing your water levels so you may want to just google a few options or videos to see what is easiest or best for you.
