I have a 22,000 Gallon vinyl liner pool in Northern Kentucky. I check my chlorine every evening and add 10% Chlorine to bring the level to 8 ppm. Over the next 24 hours the chlorine level will decline by 2 - 5 ppm. I usually add between 50 oz to 100 oz of 10 chlorine per day. I have crystal clear water, don't add any other chemicals and never shock. I have tried lower chlorine levels but have had problems with algae. I have a very low Cyanuric acid level since I don't use Trichlor Pucks. The Ph raises with this regime so I need to add acid about once a week and occasionally raise the alkalinity. Remaining chemical levels do not fluctuate enough to worry about.
