Strange Lump

[Squeven]

I found this red limp in the back of my BioCube 32. It was solid when I pulled it out with a turkey blaster, and loosened up when I put it in a cup. It doesn’t feel like cyano, and it was only in one spot.
Testing parameters, will update when complete.

Could be some other algae covered with cyano???
