new 65gallon tank.

Nice The problem I think you would have with the K1's is that they won't push the water F-A-R enough and you will end up with dead spots in the middle. My K2's did not "look" so big once they got covered with coralline.

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.
