Unlike plaster pools that must have x-amount of calcium to prevent etching, the CH in our FG pools is mainly to protect against potential staining. I'm assuming your steps are white, and if there were any potential color changes or staining, you would see them right away. I wouldn't rush to increase the CH in your scenario just for the steps, but would continue to monitor them for any spotting or discoloration that may require treatment later.
