This is all coming from a homeowners perspective, so if I come across as clueless or uninformed, I apologize. In my back yard my neighbors and I share share a pond thats about 1/4 to 1/3 of an acre. The pond is natural and is springfed, yet due to its low elevation with respect to the land around it, it sees very little wind. We treat the pond yearly and overall the water quality is good. However, a couple of times in the summer we do experience come algae blooms and experience some mosquitos. I am floating the idea of installing either a fountain or aerator to the pond to improve circulation in hoped of reducing the above problems, if either of these would reduce the problems. I think an aerator is the best way to go, but given that the bottom of the pond isnt flat, is this still the way to go? Also, without knowing the depth of the pond, does anyone have any idea how much something like this might cost to purchase/install/maintain? Who would install such a device? I already sent away for a catalog of some products recommended in this forum, but wanted to get a feel as to how big of a project this might be. Thanks in advance, I really appreciate it.
