Could use some help identifying what this stain may be and steps to try and treat it. Surface is Magic Marcite Aqua Pearl Mini Pebble. There is only this one stained area around one of the two bubbles that is on the sun shelf. Brushing with nylon brush has not help reduce the stain. Pools is under full screen enclosure.
