We just recently bought an intex 16'x48" ultra frame pool and the SWG. My husband insisted to fill the pool with our well water which is VERY hard water and full of Iron.. Well the water was brown so we used MEtal Out and now it is green. SO do we have to do anything to the water Before we add the Salt and start up the generator to get it clear or just start the salt then figure it out from there? We were told the SWG was the way to go and was easier.. But all i know is that we have to add 125lbs of salt and that's it..
