Better question is: What is the right sized refusium to handle a 75 gal tank.
Or, maybe even a better question is: Is there a good ratio of tank volume to refusium size as a good rule of thumb?
I would figure that the bigger the better, but how small is too small. Gallons and sand surface area/volume of sand?
