I have both the Bojo and the Green Monster Underwater light. The underwater one is in about 4 feet of water right under the Bojo which is mounted on a corner of the dock. Both come on at dark and the small bugs gather around the Bojo and eventually get struck by the spinning mono and fall into the water. I see quite a few very small fish and an occasional bluegill in the water waiting for the bugs to hit. However I don't feel it is all that effective in either keeping the bugs down, or feeding the fry. It does create quite a mess around the light because the spiders build webs every night. Both are fun to have and a conversation starter but I can't really determine if they help that much in pond management.
