I have a buddy that works for a pool supply place that his uncle owns. I will be getting my CYA, Muriatic Acid, and Liquid Beach from him. He also said they put what they call a "board" on pump house wall that has a tube that goes directly to the pool. Has anyone you know used a system like this on a pool as small as 20,000 gallons? They do mostly YMCA type pools. I just dont want to make a simple process harder by trying to keep up with a chemical feed system. If it will make the process easier, I am all for it. Just wanted to get some thoughts on this type of setup. I start my dig and build this week and am getting really nervoes, but think I have read and studied enough to get this accomplished. Also, would it benefit me to have my municipal water tested before I start the pool so I would know how much chlorince to start with approximately? It is going to be memorial day weekend, so my wife woudl not be happy with me if this process did not go smoothly and the pool build carried over to Monday.
