It is definitely possible to create a wave with the 7096, but it will take some experimentation on your part. Put the pumps on channels 3 & 4 of the controller. Then check the 'Wavecontroller' box in the software and push Start. Now watch as the controller slowly increases the timing. At some point, I'm assuming based on your tank size it will be fairly early on, you should see the wave start to form. You can then click Stop and fine tune the Seconds setting manually.
If you're unable to get a wave this way, then you'll want to reposition your pumps and try again. If you want to post some pictures of your tank I think we could give more specific advice. Good luck!
