I am currently using two refugium and have a question on the HOB. I just got a hang on back refugium, and don?t know the vendor. The return which looks like a pvc pipe going back into the display tank, I can?t figure out the correct size. It?s not neither 1? or 1 ??, and I was looking for a way to adapt it so that it won?t cause much bubbles on the display tank.
What can I do to reduce the amount of bubbles coming in to the display tank?
