It's a thread algae and up your co2. Trim what you can off, an sae will munch on this stuff.

Thanks was worried was Cyanobacteria. Will pop in an otto or two and see if that helps.

In my experience, Ottos don't touch this stuff. Physical removal and increasing flow and CO2 is the only way. Thankfully, it tends to pull out fairly easily, especially when wound around a toothbrush.
