Elsie,
I am far too new a pond owner and much too inexperienced with most of this to be able to provide much more than a report of my own conditions.
I could easily place two diffuser sets but the fall location is in the middle of the wading area we swim in during the summer and so I would not want the risk of entanglement. Moving is not that big a deal I just need to plan better for next year.
Currently I have triangle of 3, 9" neoprene diffusers supplied by a one and half inch line running back underground to my barn approximately 75' from the edge of the pond where it is attached to an Eco-7 pump. The water displacement in my little 1/10 acre pond is amazing and I attribute that displacement to how quickly my otherwise sterile body of water sprang to life and maintained it's health through the entire drought while others around me literally spoiled under the heat and dry conditions. Also the triangle is attached to a weighted plastic milk crate to elevate it 15" off the bottom. This was a modification I made within the first week of operation in that I quickly found that having it directly on the bottom caused the clay in my new pond to become constantly suspended. Once elevated the pond cleared almost overnight and never turned back.
I have been monitoring temps at three depths and so far have been pleased to find that they are holding very close to NOAA reports of nearby natural bodies of water like Lake Erie, Indian Lake and other large reservoirs. I figure if mother nature has it under control on those unmanaged bodies of water who am I to argue.
I just did my morning walk around the pond and checked temps. 60 degrees at 4', 57' at 6' and 55 near the bottom of the deep end in 11-12' of water.
Like Cecil had said given that I have only trout in the water for an over winter grow out and harvest I doubt that super cooling will be an issue for me. Here is hoping anyway.
