strange green algae

[mvm]

I have this weird green algae growing on the underside of my rocks. It's not that big of a deal, but I can't figure out what eats it or how to get rid of it. It can be blown off with a turkey baster and is dark green. It's only on the underside of my rocks. I will try to get a pic after the lights come on.

Looks a bit like green cyanobacter.

That's what I was thinking, but it's strange that it only grows on the underside of the rock. Maybe a flow issue? I know I need a second mp40...
I never add chemicals to my tank, but would chemipure help w/o any adverse affects?

Chemipure can kill everything in your tank if you don't follow the directions very carefully.

Chemi-Pure won't hurt, it's an adsorption resin.

Chemi-Clean is the product that kills cyano and is a risk if you don't do it right. That's a drastic measure for what amounts to a small issue at this point.

If it's just on one rock, I'd try vacuuming it off when you're water changing. Adding Chemi-Pure may help, but it may not solve the issue either.

Didn't know there was green cyano, I though it's alway a red/brown looking one.

chemi-clean will work fine as long as you follow the instructions to the "T".....I was always concerned since I dose vodka that this stuff would wipe out my tank with all the extra bacteria that I have....nope.....
