Patriot, so you have six k4's total? What kind of corals? Do you ever have issues with too much water blast on any corals? Or the sand bed blowing off the bottom in spots? Whats the closest you've kept a coral in front of one of the k4's? Also, one other curiosity, do you keep the front piece on all of them that directs and concentrates the stream, or have you taken some off? Thanks.
