This showed up a couple weeks ago and hasn't grown or shrunk.... Anybody?
Looks like cyano to me.
After researching it that is kind of what I thought, cyano is also referred to as red slime algae correct?
Can you suck it off the sand while doing a water change?
Yup red slime and cyano are the same thing.
You can suck it off, but it's just gonna come back if you don't correct the problem. Do you have a lot of flow in that area? What is your phosphate level? And what kind/how long are your lights on?
