Thanks again Mike.
I think I will really have to think about it all.
The advantage to me of the Wavebox is that it will give exactly the flow I want to add and its in the tank (not half in half out).
The advantage of the Vortech's is that they are smaller.
Actually the only reason I am even still considering the Vortechs is because I think the Wavbox would be ugly but then again the vortechs may even look worse
