We just set up our Intex AG 15x42, metal frame pool yesterday. Its been properly stored for over a year and I can't remember what to use when starting it up. Apparently the Intex website says the pool holds like 3800 gal of water. We have country water(well water) so its a hard water that we'll be filling with. I want to head to the store today to get what we need to put in the water, but don't want to start filling it till i know what I'm buying. Can anyone help me out? Kids are anxious to get in it..so would like to hopefully have it up and running by this week sometime. It has the original pump to it too.
