Orange Spots on Tiles and Pool Walls

Posted by RollTideTX (My Page) on

I need some of the experts here to help me identify these orange spots appearing in my pool. They are forming on the water line tiles and on the pool walls - there don't appear to be any on the pool floor that I can tell. The ones on the tiles wipe right off, but I have to brush the ones on the walls pretty good to get them to go away. Any ideas of a) what these are and b) how to get rid of them. PH is at 7.6. I will have to get the other test results and post them later.

I would get that water tested for metals today.
Looks like it might be sequesterant time.

Try some crushed vitamin C tab in a sock for 20 minutes. If it's still there, it isn't iron. Try a trichlor tab for a few minutes and see if that makes a difference. If it fades, it's organic. Shock and brush thoroughly.

Thanks guys - pool builder thinks its organic and wants to shock treat the pool. I am going to try the approach suggested by Scott.
