Do Coop test strips test free or total chlorine?


Recommended Posts

My aquarium coop test strips always show no chlorine in my tap water. I don't know if that means my water has very little chlorine added, or if it means my city uses chloramine and there is no free chlorine available to register on the strips. I've called the water company in the past and been told they use chloramine, but the latest ccr claims they use chlorine. I'm just searching for a way to tell for sure. Sorry if that came out confusing!
