Sump question
I have noticed that the usual sequence of peoples sumps is intake compartment with skimmer/ refugium/ then return. Why is this? Wouldnt the refugium benefit more if the skimmer was placed after the refugium?

I have had many sump designs, and like my current setup best.
1. Display tank flow enters skimmer compartment at end (semi-recirculating zone), and overflows to center chamber filled with LR & eggcrate (Berlin/benthic zone) 2. With a ball valve, display tank flow is also metered to a refugium section at opposite end, which has it's own sand or mud bed. The water movement through this section is slow and doubles as a pretty good pod factory. 3. The center chamber is where water scrubbing (Rowa, etc.), and water monitoring/adjusting is done and is also where the return pump draws water. I think the biggest hurdle with a center-draw sump is micro bubbles, but solved if there is a sufficient pile of LR (or like) over the return pump inlet. This can be done with a minimum of baffles which can be a waste of precious space if you ask me... |
