Sounds like a perfectly simple system to me. Like you said, it isn't a bakki, it is a cheap way to accomplish the same thing while avoiding the high cost. Dr. Roddy has posted pictures of a similar principle using upflow columns with lavarock exteriors for the water to spill down as it comes out of the top. Anything that will expose agitated water to open air will serve to degass and aerate. In our pond we use a stream bed with plenty of rocks to break up the flow to do much the same. Your simple filter accomplishes much in a very compact space.
