The thing with clay is it is backbreaking, but you know it is possible. With these rocks, at times I just didn’t know if I was going to get them out. But doing it like a puzzle I eventually got one then the next and so forth out. To get a big one loose has been more gratifying than once I actually get it out. For the last ones that I cant manage to get out, I talked to a friend that puts up fences and he uses something like a hammer drill to break rocks apart if needed. He is up in Granby so I may go borrow it to get the last rocks on the left side out. I got the last rock out on the right hand side last night. I wanted it out so that I didn’t have 2 separate deepest points as I figured one would eventually accumulate crap. It is getting harder and harder to get these rocks out as I go deeper but Im almost done. Last night I also dug a hole above the pond close to the fence where I can put a 100 gal 52" x 31" x 25" feed bucket for my "skippy" filter. I need to get to tractor supply thou, and they are an hour away, but there is one on the way to Granby so... Im going to get a tetrapond 1200 from Lowes for $115 + some hose and stuff. The firestone 45mil EPDM 20'x25' liner is $288 from liners.com shipped. Going to use concrete to smooth the pond where needed then cover in carpet, so shouldn’t need any underliner. I have some sound deadening foam and vinyl (
Vertex barrior pads and
Ensolite) that should be safe (made of pvc and vinyl) I could use if needed.

I cant see the pics here at work so not sure they are right...I think this stuff would be good for using on top of the liner as it wont mold or cause problems like carpet would.
Thinking I need an overflow, but maybe it just doesn’t really matter. I have a drain that is for the rear gutter that I can pipe it into but if it overflows and just goes behind the liner and sinks into the ground what does it matter? Ill just make sure the front side is lower where I am building it up with rocks so that will be where it will overflow so not to overflow on the far side toward the hill and fence where the dirt is. I also need an outside electrical socket, but my circuit breaker box is already messed up/ overfilled incorrectly from the previous owners. Another PITA.
