Tunze Wavebox, worth the investment?

[Stones]

Thanks for all the replies. I knew that the wavebox was just to supplement existing flow as I already have 2 vortech pumps that serve as the main form of circulation in my tank. However, due to the directionality (more like lack of directionalilty) in which the vortechs must be pointed, I have a few low flow spots in my tank which I'd like to eliminate. By the sounds of it, most people noticed an increase in polyp extension. Has anyone noticed more uniform growth patterns or increased growth rates in sps corals after adding a wavebox?
