Heron floats are a relatively new product. They consist of plastic rings, which clip together around
the whole pool inside edge in a double row, where most planting shelves and shallower waters are, or
anywhere where your pool is shallow or exposed. You can even cut holes in them to accommodate tall plant
growth. They are easy to install and to unclip to clean, and they are more discrete than the traditional
pond net. Best of all, herons do not like walking on them!
