Think if the test were to take place, it would require alot of resources like space, manpower, financing?
Variables needed to be taken into account are numerous. Besides technical variables that need to be kept constant, so do physical factors. These would include the amount of D.O.C in each tank, specific gravity, pH, kH, temperature, etc. All these physical affects the viscousity of seawater, which can greatly affect skimming performance.
So in summary, it would be a huge challenge. However if it could be done, I'm sure we can attract international attention from fellow reefers in RC, etc.
