Should u ever turn the lights off in the refugium
The photosynthesis process in the macro algae needs dark to complete the cycle
What? No it doesn't.
Photosynthesis can occur 24/7. If your referring to the "Dark Cycle" that is a term that refers to the final stage of photosynthesis that doesn't require or use light. But it can certainly be present.
I shut lights my dump lights off in the day for pH balancing and to get my pods more active in the sump in hopes they will get carried into the return.
