Brushy Mountain was selling Bee Aquafiers but they are now in their bargain barn. It was basically a plastic container, you fill it with water, place some floats in it (pool noodle cut into 1" or so sections), thin silk type cloth draps over the container and rests on the noodle sections, and if you have a lid you can cut a big hole in the lid and snap it over the cloth that way the cloth does not fall into the container. It was called Eli's Bee Aquafier. I thought the cut up pool noodle was pretty neat idea!
