We are experiencing what the pool store has told us is "chlorine lock out" I have added 18 lbs of shock to the pool over the past 3 weeks and still am not getting a chlorine reading when testing the water. The pool is 33000 gallons. Can anyone tell me how to get past this. We have had the pool 15 years and NEVER had any problems.
