I bought one of the Taylor test kits. When they 1st came they put in 6lbs of chlorine however I haven’t heard anything else.. have found multiple chlorine tablets (6) put in the skimmer basket though (about the size of a hockey puck)Glad to see some progress. Are you using one of our recommended test kits now? You need to find out what random chemicals your "helpers" have put in the water or you may never get to the end of this.
