Some type of algae

[AdamHorton]

This stuff is growing everywhere in my tank and I haven't been able to find pictures of it on any of the links here. Any ideas?

looks like cyano, or red-slime. It shows up when you have too many nutrients in your tank (usually phosphates or nitrates)

agreed. cyanobacteria.

Awesome, I had looked and that was the closest match I could find but none of the pictures looked remotely like it. Thanks

We have a good article on it in our SW article section.

I had this stuff in my 55G for a while, and it's definitely cyano. It's so freakin ugly. Took me a couple weeks to get rid of most of it. Not sure about you, but the cause for me was the lack of water changes lol. I had slacked for a couple weeks and this stuff went rampant.
