I've been talking to Jim Glennon at Malibuwater and he wants to sell me a 80w solar aerator. Don't know anything about it other that what I just told you and really have no knowledge of any of these systems in general. Also, while there may be a spopt or two where the water is over 3 ft, they would be few and far between. Generally the pond is very shallow. Nearest power probably 1/4 mile away.
