I used the bug light advertised in Pond Boss for years and you won't believe the # of bugs it will knock into your pond. The only problem I had was that at time there were so many bugs and given just a little moisture it would clog the fan and I would have to clean out before it would start the fan again. The bream loved it and would stay all night. I was lucky enough to have electricity close to pond so that was not an issue for me. Just wanted to share my experience.
