I got it,,, I'm not that impressed,,,, It's no defence when the pond freezes over and that's when I loose most fish. I keep the pump going so that it doesn't completely freeze so that gases can escape, and have seen 3 herons sitting on the ice at the same time, ( a myth that they don't feed together so have dispensed with the services of the hideous plastic heron). This year I know he has waded in because I noted the oily film floating on the water. So, he either lands right in it, like a harrier jump jet, or he's able to step over the double ring!!
