does anyone know of a way to remove rust spots in a gunite pool? we can not drain it to repaint it because the water table is to high. thanks to all.

First make sure its rust. Hold a vitamin C tablet on it for about 30 seconds. If it starts to come up, its metal staining. Then follow this....

If it doesnt come up, you can sit a cholorine puck on it for about 30 mins and see if that helps.
