That last light was strange, why would you want a floating purple ball in your pond? The link says only for non-clorinated places. Wouldn't the lights attract bugs? We have bats that live in the next door neighbors attic(they don't know it, as they just bought the house last fall) and I love to see them fly around eating up the bugs from my yard, but I don't want to attract more than whats already here..
