    Surface agitation does aid in gas exchange. A skimmer hepls get oxygen into the water.
    All gases are more soluble at colder temps so colder water will hold more oxygen than warmer water.

    Hi Leon

    In a typical marine aquarium water is oxygenated through stirring of the water at the surface(flow pumps etc), if you have a sump air is pulled along with the water when it runs down the overflow pipe to the sump, also a skimmer probably mixes the most air with water during it's operation.

    Salt water also has less desolved oxygen in the water compared to fresh water.

    Also, warm water has less desolved oxygen than cold water.

    the best way of getting disolved oxygen into water is through photosynthesis, and macro algaes are brilliant at doing this.

    The surface of your water also does a natural gas exchange, thus the larger the surface area the better the gas exchange and also your water at the bottom of your tank needs to be rotated to the surface via agitation so that it can release all the co2, nitrate,s and various other gasses in exchange for oxygen.:)

    and at night this is in reverse so to add to this, make sure your refugium is lit in reverse to your DT and this will help stablise the O2 and CO2
