Hello, I just purchased an above ground pool from Namco. It is a Willow size 21 inch with a 52 inch wall. I had it installed and have put water in it but am unsure of where to go from there. If someone could please let me know what chemicals i need to place in the water and in what order. I am a first time pool owner and am unsure about initial setup. Thank you in advance for all your help.
