I have both. Pretty sure its cyano, its a blue/green colour and slimey looking. Its on some plants, and on the bottom of the tank. not sure how I'm going to increase the flow there.
I've been reading up a bit on the cyano, both here and other forums and seen it mentioned several times that cyano is triggered by low nitrates. So if I add some nitrates (in the form of ferts I assume) this will help?
