beating the battle of bryopsis

[sansouci01]

After lots of research, I decided to give Tech M a try to get rid of my bryopsis. So I got my magnesium level up to 1800 or so. About a week later, the bryopsis started to disappear. It's been about 2 1/2 weeks and bryopsis is about 90% gone. What's left is a thin layer of green on the rocks. seems to come off fairly easy with a brush. Is this part of the bryopsis or is this another type of algae? Either way, I'm starting to love my tank again..

Maybe post a pic... Bryopsis is hair algae. Maybe the thin green layer could possibly be cyano.
