Hello! We are in the process of building a FG pool. This will be our second pool with the first being a concrete one with a DE filter and chlorine tabs. We also used a pool store to test the water. As seen from my sig below, many things will be different including using the info/help on this site to test and maintain the pool water. I’ll update the info below as I learn more about it (too muddy outside to look at the exact model #s). Photo showing where we are at today:
