cyanobacteria. aka red slime. you can use chemiclean to remove it but you gotta figure out the cause. check your nitrates and phosphates with good test kits.

im going to remove most of my sand being that it is 7 years Old and I took it from friend when I bought his tank back in late December.. I screwed up and didn’t wash it. I just poured it all in the tank... with that being said, I’m making progress. So far.
