I seem to have what is either Algae or some sort of stain. My free chlorine has been elevated for over a week and have brushed daily and it does not seem to be helping the stain. When I look closer under water, it has a brownish tint to it. Any advice? Picture below, although I know it is hard to see. TYA!

Welcome to the forum!
Algae will brush away. To test for iron, put a handful of Vitamin C tablets in a thin sock and crush them up a bit. Then put the sock on the stains and hold it there for a few minutes. If iron, it will go away.
I suggest you read ABC's of Pool Water Chemistry.
