1st time owning anything bigger then a baby pool. just filled our 16×42 Summer Escapes pool. thought it was on pretty level ground. NOPE.. thes about 18 inch difference in the levels from one side to the other. So not sure how much water is in it. we are getting the floating 1" pucks. what else would we need for it?
You need something to test the water with, test strips would probably be ideal for a quick check of the water quality. After testing, you want to make sure that you are controlling your chlorine (with 1" pucks and perhaps shock as needed), pH and total alkalinity. There are chemicals clearly marked for adjusting the pH and alkalinity if your test shows that is needed.
