We are building a 42x31x20 Lagoon pool. It will be about 37000gal with 48" walls. We haven't made any decisions yet regarding equipment. We haven't decided on a pump, filter, swg, lighting, solar 12 -4x10 (Fafco, Techno-solis, Ecosun) or an automation system. Ideally most of the equipment would be the same brand. I was hoping to get some input on what I should get. The solar system will be ground mounted on a wooden rack with a short run of about 15' to the pump. I'm planning 2" pipe for the pool plumbing. I'm trying to have the most efficient hassle free pool setup. Looking forward to your input!
