I have been adding liquid bleach to my pool ever since I joined this forum. I was always careful that what I was using was plain regular bleach. Somebody up here in maine got chlorine poisoning from mixing two different types of beach. The bleach that I have been using from walmart was plain bleach, so I thought. Some of the bottles said "with fabric softner" I don't know what that is. So now I buy my bleach from the pool supply area in walmart. Any body else notice fabric softner on the label?
