I have a refugium with pom pom macro algae. I run the lights during the day and my pH varies from 8.0-8.3. To reduce these swings, I understand I can run the lights at night instead. I was thinking of trying it but I'm worried about my copepods. They come out of hiding at night it seems and my clownfish love to gobble them up. I'm afraid if it goes dark in the refugium, they'll emerge, go into the pump and be immediately eaten by fully awake and aware clownfish. Does anyone have any insight on this?
