Well, the good news is I'm pretty sure the iron is gone. Not only are there no stains, the stains on the white stairs are completely gone. I have a pump house and the plumber is coming tomorrow to reroute the fill source from the softener.

I did use some clarifier before I left town. Water looks pretty good, blue with algae debris on the bottom. Unable to filter as needs to go to waste. Will wait until tomorrow when I know source water is free of iron. Certain it will need to be done several times but can see bottom.

I ordered the phosphate test kit. I wouldn't be surprised to find them as there is a lot of farming where I am and this is some tough algae. Will test pool and fill water. Vacuuming to waste and replacing with good water, we may actually be able to use the pool next week. Plan to resolve any phosphate issues definitively before I close the pool this year.

Can't adequately express my gratitude to all of you for the guidance, support and concern :0)
