Lets see where to start....First off the inground cleaning systems are not good. Unless you have a great deal of money and patience. They are prone to problems and when something goes wrong it is time consuming and expensive. The deck surface. I like a maintance free surface so I like stamped concrete. Coping is a matter of preference I think. You may want to look into a safety cover. It is an electronic cover that is built into the coping and opens and closes with the turn of a key. They are great and reduce chemical consumption.
I think most prefer a cartridge filter. There are plusses and minuses to all systems but that seems to be the ones that people prefer these days.
I built my own pool. You can email me romansone16@gmail.com. I can share photos, stories, tips, tricks and funny stories.
