No bubbles I did blow it off the rocks with a baster.
If it blew off like a carpet of material...it is cyano. Check for phosphates, make sure you have lots of water current with no dead spots, and be very careful of over feeding.
Remove as much red algae as you can and do water changes once each week to get rid of it. Don't use chemclean or Red X just yet. Try doing it natural first. It may take a little longer to be rid of it but cyano gets immune to chemclean and Red X.
