Photosynthesis in plants and algae produces oxygen. Respiration in animals and fish uses it up and produces carbon dioxide.

reading my post now, that is what I was trying to get out I guess I posted the direct opposite of what was supposed to be implied, but with that being said..
- If the algae doesn't produce enough oxygen in the water during the day it is possible for your oxygen content to deplete during the night. The dying organic matter and algae do use up oxygen at night along with fish. If I remember that correctly, its more relevent for a pond and algae blooms but I would assume there is some relevence to aquarium life. I guess that's where your Skimmer would come in to remove the dead oragnic matter.
