Ok ladies, I might be able to assist with some pointers, however whips and handcuffs and other husbands sounds like a way different kind of forum... LOL
It is an 1800 GPH pump to circulate through the bog. It sits on the bottom at the opposite end from the bog. In the past they suggested to go through your rocks, out of the pond and to bury the line under ground before coming back up on the bog end. That is outdated thinking at this point. I went straight across the bottom with flex hose. It is connected to 1 inch PVC that is coming through the bottom of the cinder block wall. That way if there is ever a blockage or problem I don't have to dig up the yard. Less turns in PVC and no major changes in hight mean less resistance so I get a truer amount of water circulation. The PVC under all of the gravel is shaped as follows...

I even ran a stalk of pipe up through the gravel so that it ever get full of gunk in the PVC I can run water or even force air down through the PVC to flush it out.
There are 2 ways to do the wall. I have them interlocked but it allows the water to seep through the miniscule spaces between them. This way water comes up through the PVC and filters through the rock and then clean water seeps back into the main body of water. I had added a bog a few years ago retroactively to my other above ground pond. The only way to make it work was to build a box at a slightly higher elevation, fill the new box with a liner that overlapped into the original. This makes the bog self contained and creates a waterfall coming off of the bog. It works just as well but I didn't want a waterfall in this new pond plus it would have been tougher to do the liner by going up and over the cinder blocks.
There is no bottom drain. I don't have a lot of trees. This type of pond is what they have been doing down here in Texas for about 5 to 7 years. It doesn't matter if it is 50 gallons or 10,000 gallons. The principle is the same. I have good water quality and the water is crystal clear. Even my 500 gallon had no sign of string algae throughout the winter.
This is very close to the pump I bought. I have a large basket assembly to stop large debris like leaves and such from entering the pump.

Hope this answered some of your questions. If you want more info on bogs, this pdf explains just about everything...
