Ok I am possibly buying a Halloween urchin tomorrow but I want to see if my tank has enough algae for it. It’s about 2 months old. I haven’t cleaned the glass yet, it is teaming with copepods. My parameters have been solid, doing water changes of 15-20% weekly etc.
Think an urchin has enough food here (only white light)
