Can the water samples from the top of a pond and the bottom be different? If yes...How in the hell do I take a sample from the bottom?

Yes, depending on how deep the pond is and where the thermocline is located. The water below it may not contain enough oxygen to support cold water fish such as trout, while the water above may be to warm even in the colder months, depending on where you live. To take a sample you would need to rig a weighted jar with a spring loaded cap, and a pull string to open it. A simpler contraption would be to weight a container with an attached hinged lid, open and openend facing down, allow it o sink then pull on the string to right it and allow it a few seconds for the lid to close before retrieving it. It may take a few tries. But if you are stocking a pond, it is well worth the time to make sure that the water will support the variety of fish you are planning to grow.

It depends on what your sampling for, but yes, they can be different. To get a sample from the bottom, you can use a container that will not open toget the sample until you have it in place, or insert the sample bottle upside down until you get to the bottom, then tip it to get the water.

if you have any aeration or water flow, there will be no difference from top to bottom. even without, the difference could only be minute. not enough to affect any fish or whatever you put in it.
