With a horizontal circulator you are continually moving the water sidways in one direction and should be able to aerate much larger surface areas but not aerate as deep into the water column, does this sound right?
this made me think that, in general, maybe the real difference is bottom diffusers create vertical convection cells and circulators create horizontal convection cells....and how these two different types of convection mechanisms affect the pond parameters (DO profile, temp profile, etc.) and which are more efficient for what types of ponds or pond objectives?
