I've ordered an Intex SWG which will arrive on Monday. I wanted to add the salt on Sunday to be ready to run the SWG when it gets here. I have an Intex 4300 gallon pool. I'm going to Leslie's this morning to get salt test strips. Should I only be concerned with the salt level so that I know how many lbs. of salt to add? Do my current FC and Ph readings have any bearing on how much salt to add?
