That’s the ticket for a big tank. or a medium size too, if you turn it down a bit. the Gyre flow theory has been around a while. its benificial for corals, and tank cleanliness and proper biological filtration. this pump should make it a reality. a smooth, strong, steady whole tank flow. much like the ocean currents or the gulf stream. aerating, feeding and clensing the system. I think its a good thing.
BRS also has it too.
