What are the dimensions (neck size, body dia & height, etc...)? I don't like going by ratings since different companies rate things differently. I don't see from the pic where the air is being injected into the skimmer. How is the air being injected into the skimmer? Venturri? It kind of looks like there may be a hole in the pipe right after the pump output. Also, is there any pics of it in action?
