Grass carp are a great fish to have around. I know the guy that invented them as sterile plant eaters. The eggs will still hatch out though since it is the males that are effected and regular carp or KOI could easily take care of that. It sounds like a great setup to me, if things clog up then simply burp the ends to clear them.
