My question: What are your thoughts for the maximum chlorine-ppm to use when closing your pool with a vinyl mesh cover?
My wife came home from the local pool store with 30 litres (7.9 gallons) of 12.5% liquid chlorine for the final pool closing shock because thats what the pool-store recommended.
Using the http://www.poolcalculator.com I calculate that the chlorine level will increase by 63ppm! So the pool company is suggesting the chlorine level be about 68 ppm before I cover the pool?
Our pool is:
60000 litres (15850 gallons) 14'x28' in-ground vinyl we are in southern ontario canada.
chlorine sanitized by 3" pucks/feeder and granulated chlorine
safety-mesh cover for the winter
pool water is balanced as per TFP recommendations
Thank you for your recommendations!
