I would have to agree with Delphinus and Stones. The wavebox to my knowledge does not add "flow" to your tank just "water movement" giving you the wave effect. You can get the same effect with 2 vortech's while still adding "flow" (3000 gph with the MP40W). So if its flow your looking for i would have to say vortech. JMO as I am still a "noob" in the hobby after only 1 year into the saltwater world.
P.S I love my vortech
