Before exploring using the proposed tube diffuser, I would as the first test move the diffusers to one far end of the pond/lake. Set diffuser/s on the bottom in 3 ft of water. Then measure the water temperature profile at the center and at the opposite far end at 7-8ft of water. I use 7-8ft of water to see if mixing depth reaches 8ft deep. Another option would be to put a diffuser at each end or side of the pond on the bottom in 3 ft of water. Measure water column temperature profile every 2ft at the pond center. Based on the results then formulate a plan for the next winter.

Highflyer from Texas says his non-aerated large pond is 14 acres. Average depth of the shallow end is around 3-4 feet. The middle of the pond is a very lazy V bottom. The average depth is around 8 feet with a substantial channel towards the east side. The deep end is at the dam. The average depth of the deeper water is around 18 feet but there is an "J" of deeper water in front of the dam. He regularly check and the summer thermocline is usually at 11-12ft.

So my thoughts are if one has a 10 to 15 acre or larger pond that has a thermocline depth of 11 to 12 ft. Does one need to aerate this type of pond when the thermocline is 11 to 12 deep. Keep in mind that water should be routinely mixing down to this thermocline depth, then why aerate this pond? What is the benefit????

Bill,

The reason I am interested in aeration on my big pond is I want to have beneficial bacteria working for me on the bottom. I also want to open the entire water column during the summer months to lower the stress levels of my fish. Next, I want to lower the surface temps during the hottest part of the summer by mixing the cooler waters from below. Finally, I use a syphon pipe as my over flow and want to rid my pond of excess nutrients and stale water so having a good mix might be beneficial with this task as well.

Thoughts?

Highflyer - All very good reasons to aerate a pond. I always wonder at what point does it become not financially practical to aerate larger bodies of water especially when by far the largest majority of the surface area is at or less than the normal mixing depth of similar sized local water bodies?

QA if it takes a setup like the J pipe to make this lake work I will do it. I am hoping there is a simpler solution. MNFish is doing a bunch of experimentation and is hopefully going to post his results. All things considered I think his conditions are very very comparable to mine. I have deeper water, he has much colder temps, I have a lot more snow and we both get about the same ice thickness. I have the elevation thing, but not sure that means much more than a de-rate for compressors. All in all I think any testing he does to prove things out will work for my place as well.

None of my small experiments this winter will gather enough repeatable data to draw any solid conclusions!

I really like that j-tube design or some variation for my shallow ponds! I would like to find a 4-5" membrane diffuser and prototype one this winter.

Pardon my ignorance, but it seems to me that if you have a good mix you won't have stale water?

What am I missing?

Augie,

I will never have a complete mixing using two or three diffusers in the deep end of a multi acre pond, so the stale water at the dam will be sucked out first. After that water is gone, I want to try to remove excess nutrients. The mixing that happens will allow the partially mixed water with a higher nutrient load to be next.

Hope this helped. Sorry for the confusion.

Ah... I think I get it now... aerate the shallow upper end, draw from the deeper lower end...

This stuff is all still pretty new to me. I scratch my head a lot trying to follow some of the concepts that are described.
