Hi JimB, welcome to Pond Boss and thanks for posting.
First off I would recommend that you read this thread and all of the included links...
Aeration archive. Solar aeration can get very expensive, very fast depending upon the size of your pond.
Before I spent a dollar on aeration I would contact one of our Pond Boss aeration vendors and discuss your pond and your aeration requirements.
Many folks have done just fine with do it yourself systems but several have had catastrophic results. IMHO an improperly designed or implemented systems can be worse than no system at all. The folks that make a living designing these systems know their stuff, there are a ton of variables to consider including (but not limited to) pond size, pond shape, water turn over rate, diffuser type, diffuser location. But that's just one opinion.
