I was out of town for a week and left a floater (2 tablets) in the pool and turned on the SWG for 1 1/2 hours a day while I was gone. I when I checked the pool water 2 weeks ago all was fine. I check it today and couldn't get a chlorine reading. I use the TF-100 kit and put in 80 drops!!!! The sample still didn't turn clear! My chemicals are less then a year old. Is there anything to worry about. I turned off the SWG and pulled the floater. My water has always been balanced.
Pool with spa -16,000 gallons. SWG.
