Hi Jeannie and welcome to the Pool Forum!
I hope you haven't opened the containers of all the stuff the pool store talked you into buying(so you can take it back) because odds are you don't need most of it. What exactly did you buy?
All you really need is a few jugs of plain household bleach, maybe some baking soda, a box of 20 Mule Team Borax (laundry aisle at Walmart). The only actual 'pool chemical' you need is about 3 lbs. of CYA -- cyanuric acid which is also called stabilizer or conditioner. We'll tell you how to add it after you repost.
You do NOT need liquid magnet, algaecide and probably most of the other stuff.
Tell us what you have and we'll help you get started. We also need to know what kind of filter you have and what size of pump.
Do you have a good test kit? That is one of the most important things you need. You cannot rely on a pool store unless you are a gazillionaire cuz you've already found they''ll sell you more than you need. Sometimes, all the stuff they sell you will cause problems and then you'll have to go back and buy more stuff to clean up from the first mess they caused! You'll need a good test kit if you don't already have one. The one we recommend is the Taylor K-2006 or 2006C (same kit, larger bottle of some reagents). If you buy it through the Amazon link in my signature, the Pool Forum makes a little money on the sale which helps us keep this form online. Only buy if the seller is Amato Industries, however. Some other sellers are substituting the K-2005 which you do NOT want. If Amato isn't listed, wait a day or two and try again. They seem to restock pretty quickly when they sell out. (While you are waiting on the good kit, from Walmart, pick up a cheap OTO/Phenol Red kit (yellow and red drops).
Your kids should be able to swim within a few hours of the pool being filled. Reply with requested info and go to Walmart and get the stuff I suggested and we'll help get you going!
