Hi, My name is Marilyn, and I am a "Retired Grandmother"

I am a Retired Grand Mother of 4 Girls who Love to Swim. My Husband recently Purchased a used Intex Ultra Above Ground 16 x 48 Pool, and as I'm sure you already know: it has 3 Patches in the thin 20ml. Liner. I want to replace this Liner with a 30ml. Liner I have had many Intex Pools now and their Liners that come with the Pool set are so cheap and thin. We are going to set this one up and I want to know how to make sure the Under side of the Pool has a VERY STURDY Start. Then, I want to know where I can buy a Really Strong Pool Liner for this Pool and not have to Spend Hundreds of Dollars. Can anyone please guide us through the Best way to accomplish a well set up Pool?

Thank You in advance, for all your "Vast Knowledgeable" Selves; who can make this a success for us and our 4 Girls plus my Daughter and us as well. lol We need a Kid Proof Pool. LOL
