Rural Setting and dealing with the Iron Content in the Water, the Iron Count is acceptable according to the Charts but that nagging Rust Stain in the Toilet Bowl & Bath Tub and especially come Wash Day on the Whites.. Anyway we had a Reverse Osmosis system along with a Water Softener installed back the beginning of December... The Stains are gone but there is still a slight color to the water coming from any other Tap than the Kitchen Sink ( RO system ). 1st Question as I discovered I had bought a couple bags of the Regular Salt, Can I mix Windsor Salt marked Rust Remover in the batch, hopefully getting the Rust Remover results? 2nd Question, the Softener has a Resin Care dispenser inside the Drum, How long would it take for the Resin to go down before I'd have to Add some more... Thanks, by the way I would go on the Manufacturers Website but it's the Multiple Choice & Questions before getting to the right department that Kills Me...
