i have a k3 and k2, the k3 800 gph runs constantly except i rigged it to put out a little less flow. and the k2 600 gph is hooked up to a wave maker along with 2 maxi jet 1200's, the k2 works great on the wave maker the k3 is hair pulling loud only when it starts. its not fun to hear that noise every 25 sec.
overall they put out some wicked flow, and well built. |
