Just bought an Intex 18 x 48 easy set pool, 5400 gal. Also purchased SWG. I'm new to being a pool owner and am worried about filling my pool with well water. We just had a new softener put in and when the water was tested, the hard water has iron 27ppm. I'm not sure about filling with softened water over a period of days, or using a Camco or other water filter. I dont want to get the brown water everyone says they get. Any suggestions?
