What do you think?
 

Does anyone know what model of pump is used for wavebox. I just read if i build my own box and add a tunze 6100 or 6200 with wave controller 6091. Then I got myself a wavebox. I this true?

There is a thread on Reefcentral about how to make your own wavebox, it even has instructions on how to make the wave timer for the box. The only tunze part required is the pump.
