Hello, I am in the market for an above ground pool. I don't need/want that big. I was looking for a round 15 foot, 48" or 52" depth. I want to spend around $1,200.00. Is that possible? Any good recommendations? For example I would love opinions on the Heritage pools Also can I make any above ground pool salt water, by buying the special generator, or do I need to buy a certain kind of pool? Thank you for any help you can give!
