Why is it that refugia have partitions at all? I'm thinking I could use PVC out from the main tank to the center of the aquarium and PVC from each of the four corners back to the main feeding into it by gravity from 17". Moreover, if the PVC had holes drilled into it from bottom to top, I could sample the entire water column from bottom to top and the zooplankton would be directed from the center to the edges by in current from the main. I plan to use a 50 gallon (or larger) rubbermaid farm animal watering container for this purpose together with a 6" live sand bed. Overkill perhaps for a 7 gallon nano-reef main tank but I am facinated by the prospect of setting up a relatively low-cost self-feeding system.
Are the partitions there simply to exclude macroalgae from the flow? [/b]
