So my head is spinning. We are looking to build our first IG pool and have never owned one before. We live in the Wylie, TX and are starting to get companies coming out to give bids. I know I am opening up a can of worms but wanted to get some opinions. Not sure what type of water treatment system to use; chlorine, saltwater, O3, Ultra UV?? I read and read and I just get "tired head". We have a rod iron fence and I hear saltwater systems cause corrosion and could cause damage to flagstone. Then there is the filtration system DE or cartridge. Just need a little help and be pointed in the right direction.
