Rick....I've got two MJ1200's and a Seio 620 in my 92 corner. The MJ1200's are equipped with Koralia wavemakers on the output....these help tremendously in distributing flow. I point the Seio620 at the surface to get a ripple effect. Obviously my 92 is a much bigger tank but by using the wavemaker attachments (and they aren't expensive), it saves on having to have more powerheads and they don't take up that much viewing room. You might be able to get away with just 1 in your nano. The wavemakers work on any size pump.
