So unless I'm missing something with these, they really only cause a circular flow in one direction, thus on one side of towering/large aquascaping and larger pieces there will be dead/slow spots plus corals only getting the unnatural flow/current from one direction vs a set-up of vortechs or tunzes set up on opposite ends. How is this going to effect growth patterns ? Just when you consider how the tides coming in and then back out or currents change. I suppose you could mount one on each side/end to get this effect. For the dead spots a guess you could use power heads but then you are disrupting the flow effect that you are trying to achieve.
