We are ready to break our pool out of the box and set it up for our kiddos. We've learned that the stock pump that comes with the pool is not effective. Please break down (with Amazon links, if possible) all the basic equipment we could purchase to keep our pool sparkling and safe for our kids. We do not know the first thing to owning a pool but since our children have lived in a small blow up pool for the past few summers- we took advantage of last summer's clearance items and made this larger-pool purchase. Any assistance will be appreciated! *we also have hard water, if that info is useful.
