at this point, you need to do a good water change using water that has RO water, and do so for the next couple weeks making sure you only use RO water from here on.
then, you need to get new light bulbs. if your bulbs are old, then they will support the algae growth. this goes for the bulb over your refugium too, as it ages the macro algae doesnt grow as well.
if you fix the water and the lights, add some clean up crew, and do a short lights out period, then you will be on the right path.
