All I've ever dealt with is the hard dark green stuff that's generally sponge-able. I left my tank for a measly three days and now I can barely see in it (exxageration)

How do I get rid of this?
(Additional; cories in the tank, so if you recommend a chemical it has to be fish (duh) AND cory safe.)

Here is a link you may find very helpful.
Scroll down to Aquarium Blackout.

If you don't mind I'm moving your thread to the "algae" section of the forum.
Thanks!

I you want a natural way you can always try RCS or Amano shrimp i heard there good with that. But i might be wrong someone might be able to give you if im right or wrong about that.

Blackout technique isn't going to work I don't think. The tank is already in the darkest corner of the room and the lights were off while I was gone yet it popped up on every inch of the tank in days. lol. Guess I'll just have to scrub and hope.

Additional: My largest Gourami, Kiwi, is not a fan of shrimp, and will kill them on sight. And my cory's food has copper in it. So that's a no-go. Thanks anyways, DrGueedo.

I was actually hoping to get some otos to see if they'd get rid of it for me when I went up for more dechlor (need to change water) but all that was in their tanks were some tetras and dark green algae. They missed a shipment of fish. Sigh.

Well, problem kinda solved. Scrubbed out two sides of the algae, at which point I noticed my cories going crazy for the stuff. Little food trails all over where it's been mowed down.
