om...
I'm looking for any suggestions for an
above-ground indoor pond.

Our constraints:
The room we are using has a solid concrete floor
and we have a space
about 10'*8' and would like the pond wall to be
24" to 36" high (36"
seems to be a max height for comfortable
sitting, I am concerned that
water less than 24" deep will get too warm in
the summer).
We don't want to do anything permanent, so no
mortar or concrete if it
can possibly be avoided.
We have dogs & cats that are very inquisitive.
I'm more than a little
concerned about the effects of a ripped liner
indoors.

Here are my thoughts so far:

Flexible liner
This seems to give the most flexible design, but
the drawbacks I see
are the potential for a tear and making sure it
doesn't collapse.
I've thought of 2 solutions to holding the pond
together:
1) stacking retaining wall blocks, but I'm not
sure these would hold
the pressure of a deep pond,
2) building a wooden box from green-treat 2*x's
with 4*4 corner
posts. I think the wooden box would be
stronger, but would it be
strong enough?

Pre-form
I haven't been able to find any large (150g)
pre-form ponds in this
area and would like something around 500g or
larger. I've seen that
these are available elsewhere and I'm looking on
the internet.
Anybody got any suggestions? The small ones are
too shallow and I'm
concerned about the strength of the larger ones
(retaining wall
problem again). I've also looked at stock tanks
which are
free-standing so no retaining wall problem.
However, there is the
shape to think about. Whatever I get has to fit
through a door, so
the 8'*8' is out and the 6'*6'*2' is at the very
low end of the size I
would like to get to (around 400g). Also, my
local farm supply stores
carry bright colors rather than black.

Stock Tank + liner
A perfectly round tank is also not very
creative, but the only method
I have come up with so far for tapping off the
tank to a bog garden or
cascade is to line it and use the liner above
the edges of the tank.
The sides of the tank would provide the support
to hold the pond
together and the liner would give flexibility in
designing shallow
areas. Problems with this one are expense and
the same problem with
pets possibly tearing the lining.

Has anybody on the group tackled a problem like
this before, or have
ideas or suggestions that I could incorporate?
Any help greatly
appreciated.
