I haven't purchased my above ground pool yet but I'm getting closer. I want to purchase the right one for my family. I want to buy an oval 15 x 24 x 52 pool but everywhere I look they don't include the pump or filter etc and that stuff I need to purchase separately. Can someone direct me or tell me what I need for the size of pool I want and is there an alternative to using chlorine? Thank you for your help!!
