This is exactly the same size pond as im building, starting with alot of frames interlocked together then lining the whole inside with insulation then boarding it all and finally epoxy resin to make it water tight, im also planning a window but not sure how big to go or how to actually fit it. Thats what im currently looking into atm, i was going to be lazy and just buy a large Koi quarantine pond lol but i thought it would take all the fun out of the design

I dont really understand what your question is though, i have read through the thread and cant really see what it is your trying to say. Sorry matey but my brain isnt fully functional today could you break it down a little so i could poss see what your saying.

Won't work.. I'm to lazy to repost my PM to you LOL even though I thought you were looking to use this just as a substrate ... still the same idea though... as well at the clay needs to saturate for prob a few feet and still leaches water through slowly
