So, my pool is turning 3 years old this month.
Salt pool.

There is a plate on the bottom of the travertine, at the top of the skimmer entrance. It is starting to rust and cause some discoloration on my tile.
What is the best way to fix this?
Should I have someone come out and pull up those two or three pieces of travertine and replace it?
Could I turn off the pump, drain the pool till there is no water in the skimmer entrace, put plastic down, wire brush it with a tool, then paint it with marine paint?
