Cool project!
I highly recommend an aeration system combined with a concentrated bacteria additive. This works well on ponds with moderate growth of benthic and filamentous algae. It avoids pesticides such as Cutrine that will harm your zooplankton populations. When this does not work, Cutrine Plus is the next step. A rate of .75/acre foot is a good starting point and should work. Be sure to use a surfactant like Cide Kick. Feel free to ask any more questions. An aeration system is always advised for a healthy pond!
