Burgermeister, I think my decision has been made concerning the Malibu Water sytem. I posted a question on their message board with all the things you asked about and got no response. I called Malibu Water only to find that the lady on the other end of the phone didn't know anything about the system. She did give me her managers phone number, which I called and left a message with your questions. Once again, no response. So if you think that you could help me build a decent quality solar aeration system, I would like to here your thoughts. Thanks in advance.
By the way, it will probably be 2-3 years before I begin to build a house near my pond. So, I'm not dead set on solar aeration if I can wait with no ill effects. I'm not dead set against it either though. Any opinions are appreciated.
