We have just finished putting up a Westminster II 27' round 54" deep AG pool with a sand 1 1/2 hp pump with a dome cover. We have not put any chemicals at all in it yet, as it is still filling with water as I type this. We would like to know what we need to do to have a salt water pool and if it is better than chlorine or baquacil (what they sold us). We decided not to use anything yet until we research. Could you please tell me as much as you can about what we will need to get this started since we have not put anything in it yet? We live in Wisconsin. WThank you in advance.
