Any advice appreciated:
I manage an oval 3 acre pond (13 acre-ft volume), max depth 9ft, in lower New York State. There are some fish, but the pond is mostly used for swimming. Currently have 1hp aerator running four diffuser heads (6-9" long silica diffuser stones on each head). The intent is to minimize blue-green algae outbreaks during summer. My rough calcs show I turn over the lake volume more than 2/day.
This year is the first year we installed the system and the aerator heads are sitting on the pond bottom. It's obvious that they're stirring up alot of sediment. While this is an aesthetic issue, I'm just wondering: is it common practice to somehow raise these heads off the very bottom of the pond? If so, what do people use to do this? Maybe tie the diffuser heads onto some old milk-crates and weight them down?
And, is stirring up all that sediment such a bad thing? Would all this stirring somehow promote the muck to be decomposed faster (such that the turbidity is only a temporary thing?)
Many thanks
Theodore
