My pool is still green but I have hope. I am waiting for the Taylor test kit - K2006 - but in the meantime I tested with a test strip. My pH and alkalinity are within range. The test strip indicates my CYA is between 50-100 ppm. I would like to get my Free Chlorine up to 15 ppm according to the BBG chart. I have 50 bottles of bleach. They are not gallon bottles but 96 fl. oz. I have about 37 gallons of bleach. How many gallons do I need to pour in to raise my FC up to 15 ppm? Do I pour the bleach directly in the skimmer or in the pool? Thank you in advance for any assistance you provide.
