This is my first time owning a pool. I went to Leslies Pool Supplies and bought some "dichlor" Chlorine granules. It is stabilized chlorine. On the bucket itself, it tells me to maintain a free chlorine level of 1-3 ppm, by adding 3 ounces of the chlorine per 10,000 gallons every other day.
However, this is stabilized chlorine, and my CYA level is 60. I went to poolcalculator.com and it recommends a free chlorine level of 5-9 ppm based on my CYA level. My question is why would the bucket of chlorine tell me to stay at 1-3 ppm if they made it and know it's stabilized chlorine and the CYA level will rise? Should I listen to the instructions on the bucket or the poolcalculator.com website?
Thanks very much for your help
