New pool owner....Ok 24 hours into SLAM, have added 18 gallons of bleach already, 6 a time, and cannot get FC above 2. Does this likely mean that I have ammonia in the pool? I did not get a CYA reading above 20 before starting, and havent added any yet. Pool is already relatively clear and see through water...Should I just keep adding dozens of gallons of bleach until I get FC to hold??
