Ok, added 4 gallons of bleach last night, left the pump running all night and day and is still currently on. Was unable to test the water until this evening when I got home from work. CL level test this evening is 0.3!!! Where do I go from here? Should I add another 4 gallons, and test every 4 hours? Problem is, I'm at work for a majority of the day - including tomorrow.
