Many thanks everybody. I will take the advice on the liner and just
redo the whole shebang.

Any comments on the pump/filter question? I think the biggest
constraint here is space. Small lot in the city and my wife has
staked out a lot of the square footage for the garden!

I would like to keep koi in this small pond if possible (getting
conflicting advice) so I'd like as much filtration/aeration etc as
possible. I don't mind spending for a compact new filter & pump, or
building a do-it-myself model. I just need to figure out the most
space-efficient design, that can ideally be buried. I posted a
drawing of possible plans he http://koiphen.com/forums/showthread.php?t=63835

Any way to get photos onto rec.ponds?

Photos only thru photobucket or website ways. There are newsgroups that
allow them.... and you can do what you did, post on koiphen and direct us
there. :-) You definitely need a bigger pond from the picture, almost
hidden by the rest of the landscaping. ;-) No grass, so I guess the hot tub
had to go. Better a pond then a hot tub any day.

Don't know if you've looked at my website, but my koi ponds are a total of
1300 gallons, 1500 w/filter, my 4 barrel in ground filters do a great job.
I use to have 27 koi at one point. Water quality wasn't so much an issue,
but the over crowding was, as they got bigger I started having problems.
Now I have 4 in the upper pond and 5 in the lower, with 3 of those on the
small side. I probably should have no more than 8. They're butterfly koi
which seem to do better in smaller quarters than their short-fin
high-classed cousins (imo).

Just this year I put a 2 barrel system on my 1000 gallon lily pond. This
may be all you need. What's nice about the 4 barrel is I only have to clean
the bio-chambers once/year, and I can run one side while cleaning the
other. The pre-filter only gets cleaned a few times/year. I run all year,
but on much slower flow November - March.
