Ted, My pond is fed from a spring that runs 11 months out of the year, which comes from the direction of my neighbor who has a septic tank and
heavily fertilized yard. (up hill from my pond)
Also I have a 120 acre corn field that water sheds
through a culvert under the road into my pond. Two
sources of nutrients I can not control or reduce.
This year after the ice melted I had 25% algae coverage that I killed with copper sulfate then once
dead raked out, then I applied my blue dye.
I have 2 very large grass carps a one koi that I have seen eating the algea. I also have bass and blue gill.
I have a large amount of water flow during a rain
that will totally wash the algea out my spill way
and with the spring too I figured I have plenty of
aeration or do I? I live in Southern Indiana.
Thanks for your input.
