Hi .. I am having green algae on the white pebbles in my tank..anyone know the cause and how to get rid of them?

I also have white pebbles in my tank. My pebbles have green algae because I'm using high light. I try to control by having a sucker fish and some otos. But cannot totally clear. Maybe you want to change brown pebbles, the green algae will not be that obvious.
