Only towards the back wall. I cleaned most of it off but you can see close to the rocks what it looked like before cleaning. My tank is in Fallow. I was running chemi blue. It didn't help. I'm thinking maybe add a powerhead? Or Dr Tim's ? I would like to improve it while it doesn't have any fish in there. Nitrates are at 20. Using RO/DI water.
