I just bought my first pool tonight. I got an Intex 24' x 12' x 52" Ultra Metal-Frame. We already want to upgrade the filter and pump. I have heard that both are inadequate. So, we are looking at getting the Intex 4000 pump and the Krystal Clear Salt Water System. My question is am I forgetting anything or am I getting it wrong? I want to order everything now so it will arrive together. My kids will be very impatient once it gets delivered. I am getting overwhelmed with this pool and it isn't even here yet. I want to make this as easy as possible.

Thank you for any advice.
