biodiversity. The rock I had before sat at my mom's for a few months without a water change. Very high in nitrates (probably around 100ppm when I finally was able to bring the rock from her house) and most everything died off it. No algae but not much for anything else either. Only a few clams and a lot of white coraline. I figured it would be a good idea to freshen up the tank with some new rock.
