I was leaning towards using only HSB in my 3/4 acre pond to control CNBG and the consensus was that nobody was sure if that would be enough predation. It was a recent post in types of fish to choose titled is one predator species enough. I would copy the link but I would probably screw it up!!! Lots of good info that may help you. I went with a mix of both... Time will tell how good of a decision that was
