I would agree, I have a 55gal with 3 Maxi Jet 1200
2 on one side and 1 on the other. I've got one half way down in the tank and the other 2 about 1/4 the way down.
It seams to work really well.
the one that is half way down is pushing water behind my LR
the other 2 are pushing water toward each other and up to the surface.
The one thing I will mention is there on a wave maker power strip, because when they were all on at once it was heating my water up to about 83degrees. Now there on a 2 minute cycle which has help with the heat. However I live in Phoenix which more than likely has something to do with it also.
