What is this fuzz???
My tank has been cycling for about a week now...no fish, no plants, no ferts, and no light. Aquaclear 20 filter running, and eco-complete substrate with some wood and rocks, and dechlorinated tap water. I noticed a small piece of fuzz-ish thing on the substrate the other day, and removed it during a water change. Today I noticed another little piece of fuzz. What is this??? It is not on the glass, but rather swaying in the current attached to a piece of substrate.
Could it be a piece of debris from the filter media? Or something from the gravel? I've had my fair share of algae run ins and it doesn't look like any algae I have seen before, nor do I think it could be since the light is never on.
