Best Red Algae Control??

[intarsiabox]

I got some neglected rock that had lots of cyno on it. I just used a turkey baster to suck it off the rocks when I did my water changes and it was soon all gone. Water changes and good circulation are key, I don't know of anything that will actually eat the stuff.

An old toothbrush does a good job on most forms of algae on live rock.

Making an inhospitable environment (i.e. clean water) is the best way to cure the problem longer term.
