Have a question on using powder chlorine. I am in the process of closing my pool for the coming winter months but first I need to get the water balance. While balancing thee water I notice the water is a bit cloudy, so I am going to slam it to clear it up before the closing. I know liquid chlorine is call for when slamming but unfortunately liquid chlorine is not available in my area (Montgomery, Al). The only chlorine available is powder, what I would like to know is will it be ok to use powder chlorine and will I have to do anything different using the powder chlorine while slamming? Any advice given will be greatly appreciated.
