I was quoted 8000 for a automatic cover because i was told it will save on cleaning and chemicals and water with a automatic cleaning will will not take much to keep the pool up. But more important i have a 4yr and 9yr boys. My BP gave me a another choice using the money to buy in ground cleaning jets and Aqua logic and Turbo Cell SWG. The pool will be 15 x 30 with a 6x6 pool spa in the rectangle pool. 4 ft on each side and 5 in the center. Then use a manual cover or fence. I not sure DE or cartrige filter. What do you guys think
