I have a 150 gallon tank. 60Lx24Wx24H. I have (2) 6105 Tunze with the 7092 controller. I have one 6105 on each end of the tank off set to one another. I just got the controller the other day so I only had a few minutes to play with the controls. But could not get a wave to form. When I press the -/+ buttons it didn't seem to change much. I'm I suppose the press the button multiple times before any significant changes are seen? Where s the ideal spot for the pumps to be? Right directly opposite of one another? Or is it possible le to ha e them off set? At what depth should the pumps be at? TIA
