So much to learn! So little time to swim! 1st time pool owners here. Thought we were getting a great deal on a used Intex XTR 18 ft round pool for $500. We've probably spent 10 times again that much for an upgraded ladder, an auto pool vacuum, a salt water generator, an electric heat pump. It's like the book I used read my kids "If You Give a Mouse a Cookie." (He'll want some milk to go with it. If you give him some milk, he'll want a straw to drink it with.....You get the idea!!! Lol)
