Possible Nanostream set-ups for an 18g

[LBCBJ]

I have an 18g tank with dimensions of 22x18x20, and am considering my options as far as which nanostreams to get (I need something to keep me pacified until they are released). It is an all SPS tank, and I am a big fan of alternating/pulsating currents. So, I was considering either getting 2 6025's and placing them on, say, 20 minuet alternating cycles, or possibly one 6055 with a contoller. Do you have any opinions Roger? Would the 6055 be too powerful for those dimension?

Also, are all the nanostreams the same size?

The 6055 can be turned down. I think 1 6055 would be ideal.

Great, I'll definitley keep that in mind
