Make sure you get your pond properly sized for aeration. A 5 acre pond is a lot different than a 1/2 acre pond. Smaller ponds can get by with a DIY system, but if underaerated, your pond can have more problems and you definately won't get your oxygen up high enough on the bottom to support a mayfly population. Very interesting topic!
Sue, aeration systems when sized properly help control and modify algae blooms in many ways, but perhaps this is a new one! Everything I'm reading supports the idea that mayflies are primary consumers which dine on algae, which is a great way to convert sunlight energy as directly as possible to fish muscle mass. I am still impressed with how beneficial my Vertex designed system was for my ponds. Interestingly, after installing the system, I remember noticing an increase in mayfly numbers. Very interesting!
