SuitUp;

As you say, you didn't follow directions.

You're situation is sorta like someone saying, well, yeah, when I got to Chattanooga, I was in a hurry and wasn't paying attention and didn't follow your directions to get to Atlanta, so I took I-75N. Now, I'm in Knoxville. How can I get to Atlanta?

The only possible answer is: "Turn around, go back the way you came, and when you get to Chattanooga, take I-75S to Atlanta!"

In your case, you've dissolved some of the stains into your water, but have no way to keep them in the water, nor anyway to get them out of your pool. You've got to re-chlorinate, or as you say, you'll add algae to your list of problems. Once you do, the stains are likely to reappear. If you're lucky, some of the iron may be filtered out.

You'd better add chlorine really soon.

So . . . good luck!

(And, let us know when you are ready to do what it takes to get the stains out of your pool . . . )
