Wave maker

I am currently looking into buying pieces to start my tank. I have a 110 gallon a was think about buying at least two powerheads. If i wanted to add a wavemaker how do you position the powerheads one at each end or same end? Sorry in advance for the NOOBIE question.

 

every tank seems to be diffrent all depends on rockwork types of livestock i would start about 2/3 up on the sides twards the back pointing to the middle of the front glass slightly upwards seems to be a good spot to start

but do yourself a favor get something with magnets i got 2 cheepy ebay powerheads with suction cups and thay work well thay have a tendancy to fall and turn my tank into a snow globe

and if i was going to make a sugestion get the hydor evolution 1400 . there a bit pricy but with good reason and thay dont move i would run 3 of them in a 110 gallon if it were me
