Do you want a "bog", "fen", or "marsh"?

I thought when people talked about a "bog filter," they were usually
referring to an upflow gravel pit? (i.e., not really a "bog").

My bog is just like the one you showed me. That's the site I got the idea
from. I just dug the hole as deep as I could (rocks) put in the liner and
it overflows into the waterfall.
