Have a few questions I have about a 2 acre lake and just got the FA knocked down quite a bit, I have a creek that feeds the pond then it empties into another creek at the other end. So I get quite a bit of run off from people upstream as far as fertilizer and such. There is no plants in it currently which I was going to add next spring to help eat up some of the nutrients. And also have a 3.5hp fountain in the center, I was thinking of adding 2 aerators as seen in the pic should I? But what do I do about the elodea will it go dormant through the winter, and is it something I can treat next spring?
Thanks for all the help!
