I purchased a 24ft round above ground pool and do not know where to start with the chemicals. It came with a Pool Breeze start up kit which included non-chlorine oxidizer, start-up and winterizing algicide, and metal removing agent. The directions say to add each of these items. It does not mention adding chlorine at all, I am lost. It does mention adding more non chlorine oxidizer weekly to shock it. Does this take the place of chlorine? Any advice would be greatly appreciated.
