Water Gardening: Pickerel rush and herons, 0 by Bertsby

I bought the rush for my small koi pond because I liked the looks of it. I had no idea at the time that installing it in the pond would put and end to the string algae. I still use a UV filter for floating algae but the string variety has been completely eliminated. I've tried a second plant (other than the rush) along with the rush but it didn't survive. Perhaps the rush was too effective. Who knows.
Heron. Nasty birds who love fish, moles and anything else that can't escape their patient observation. As we're also subject to visits from black bears I set up a trail camera which, as it turned out, is equally effective at picking up a heron. First capture caught it approaching the pond and downing a mole. Like others, I keep a bird net in place. Works for the leaves as well as the herons.
