I recently set up a 120g tank with sand and added two Odyssea 500's. The outputs are pointed just enough to create ripples at the surface. Will this be enough aeration for the fish or should I get some kind of powerhead or something else? I've always used powerheads with UGF. Not sure how to use them in a sand tank. Is there a different kind than the ones used with UGFs? Also, I plan on this being a planted tank soon.
