well...i got 2 of the nano k's... i put them near the sand bed..and they seem to push atleast to half the tank....the k2 in the back covers the rest of the front of the tank that the k.nano doesnt reach. the return line is providing the rest of the water movement for the other koralia nano in the back end of the tank.
im sure the k2 wouldnt look so bad if it was covered with
coralline...but i cant seem to be getting any in my tank....and it kinda sucks.
