Hello R2R community,
My tank has developed this very odd reddish-brown film that encrusts all rocks and parts of the sandbed that are exposed to light. I thought this was cyanobacteria so I ran a cycle of chemiclean. Didn't really make a difference. So I decided the physical remove as much as possible and it helped a lot. However it seems to always grow back during the day light cycle. Does anyone have any ideas at to what this is and how I can try to eliminate it from my system?
It's difficult to see in the photos, but it has this string like appearance and just flows with the current.
