Since I found TFPool I've been using just liquid chlorine and love having more control over my pool using it. I have a full container of 3" tabs/pucks left over. The liquid chlorine has no smell. As I understand, chlorine gives off the strong smell when it comes into contact with bacteria. My question is, why do the pucks have such a strong irritating smell sitting in the bucket? Is it the filler that the chlorine is held together with that is interacting with the chlorine?
