Hello all! I am about to open my 16x46 above ground pool. Last year (our first year) I didn't find you guys and start the BBB method until it was too late and I had already messed it up! I was able to get my hands on a salt water filter (used). Everything I have read says to just put in salt and that's it. I have well water with metals and want to know if I should do any shocking or chemicals along with the salt. Thanks so much! You were all so helpful last year!!
