Hi Deb Driesen here. While we've had inground and above ground vinyl liner pools over the years, this will be our first fiberglass indoor pool and we want to have a salt pool (SWCG). In previous pools we used Baquacil with good outcomes. Our new indoor pool will be just a small 12'x8'x4'6" therapy pool, just for the two of us. I've ordered it with a UV light and posed the question if thats necessary. The pool will be inside a sunroom and it will be covered when not in use, so not much daylight shining on the water. It will have a cartridge filter and an electric heater. Any thoughts or recommendations are appreciated.
