Multiple little rust spots

I have been SLAMing this week and today I was vacuuming when I noticed multiple little rust spots through the pool. Maybe 8 in total. I switched to my wire brush and the spots are still there. I imagine this plaster is old when we bought the house a few years ago but at least for the next year, what should I do?

Welcome to TFP.

Take a magnet and see if it sticks to the spots. It could be rusting rebar close to the pool surface.

It is not a big problem if you are going to deal with it next year in a replaster job.
