reefkprZ can you explain more about the currents you mentioned them needed, I don't know what BUKU means? What food do you recommend for the seafan to stay healthy?
BUKU means lots. *S* do you have the species name of the seafan you purchased? that would help immensly.
a picture of it wouldnt hurt either.
laminar flow is what most seafans prefer/require wich is unusual for corals, fortunatly laminar flow is easy to provide, the shape of the fan will dictate the direction flow should blow through it, you want the flow blowing perpendicular to the flat of the fan that way it has the most surface area exposed to the flow.

almost all gorgonians feed best at a flow rate of 10 - 15 cm/s
there are not many studies on the natural diet or feeding behaviors of gorgonians on coral reefs at all. The studies that have been done suggest that most gorgonians likely feed on a variety of small plankton, detritus, marine snow, phytoplankton and even bacteria (e.g., Coma et al. 1994, Ribes et al. 1998, 1999). Although these studies suggest that gorgonians will take a variety of prey items, all prey items consumed by gorgonians in the wild are very small, and gorgonians eat a lot of them.
Among those gorgonians lacking symbiotic zooxanthellae, much of the diet appears to derive from a range of tiny prey including invertebrate eggs and larvae, ciliates, copepods and other microzooplankton, particulate organic detritus, diatoms, dinoflagellates and other phytoplankton. For example, in the small-polyped gorgonian Paramuricea clavata, Coma et al. (1994) found that copepod eggs, copepod nauplii, other invertebrate eggs and larvae, and other small zooplankton (primarily 100-200 micrometer size range) prey items accounted for > 75% of the diet
