A few more things Im really not sure about. I started doing my plumbing and realized that there is not much room to plumb another herbie drain between the refugium and sump. Im also wondering about the fact that the refugium is not raised up much higher than the sump. Is this even going to work? If the refugium is draining from near the bottom and then into the sump by gravity, it would barely be a drop at all. I don't know if that makes sense but this doesn't seem to work out in my head. Is it possible just to keep them at the same level and connected through bulkheads near the bottom. That way just allowing water to flow through the refugium into the return section of the sump?
I will draw a picture
