Define tight? (Imagining Bill trying to clean filters with only 2" of
clearance.) ~ jan

Tight, as in take them off the shelf to clean them. But I'll put a drain
valve on the bottom so I can flush them. I'll also use flexible hose for the
last connection so I can take them apart fairly easily.

Not ideal, but I want my Koi. I think moving the tree and tunneling for the
drain will be big chores compared to digging the pond.
