bubbles in the oil are very bad because air does not lubricate, the whole point of the dry sump is to eliminate air in the system. Air also will compress, so your pump will have to work harder to pump the same volume of oil. I dont think there is a huge problem if the oil pressure stays up, just make sure the oil going into the pump isnt frothy which I highly doubt if your tank is big enough.
