u stated this in your anthiinae post.
"Plainly stated, though, a staggeringly simple plankton-generating refugium can be constructed as follows. Take an empty aquarium or water-holding vessel (plastic shoebox, food storage container… whatever!) and tap it inline to the system. It can be upstream from the display (fed with pumped water that overflows back down), or downstream from the display (catching water before or after the sump pump, and before the topside display return). In this empty, water-filled vessel, string a series of coarse filter pads (such as Supreme brand "Pond Master" rigid prefilter inserts, cut to size) like clothes drying on a line. A bit of strong fishing line will do well here. The thick pads are to be slightly smaller than the height and width of the water column in the tank. And, they should be given space between each pad. This will allow strong water flow through the aquarium and all around the pads. That's all! No substrate; no lights needed. You simply have a dim or dark refugium filled with coarse media suspended off the bare bottom on a string, being given a strong water flow and a food source (raw overflow water and/or supplemental feeding). It's not rocket surgery… errrr, rocket science, I mean. It's just a dense matrix with good water flow and a food source for amphipods and other microcrustaceans to grow free from predation. A verifiable pod disco! Many will overflow each day and be an incomparable natural food source (and this productive refugium cost only a few tens of dollars, at most, to build)."
am i suppose to add live rock and sand and caulerpa in a fuge like that? or is the above material all i need? thanks
