How often have you broken down your tank for a clean up? Take out rocks, driftwood, etc, and gravel vac under it all? Do you stir the substrate? I'm planning a thorough cleaning tomorrow evening and I'm going to try and make it a regular task maybe monthly. I have a heavy bioload in the tank so I'm hopeful my results will help improve conditions. There not poor now, but want to step it up a bit.
