i use a stock tank in my limited size backyard. it is 300 gal, approx. it is
bright blue, but i don't mind that. i got it at a feed store. i have
loose-stacked old bricks around it because in our hot sun, any way to keep
the sun off the pond withought blocking it to the plants is a good thing.
and it's prettier. i had a birdbath custom-made with a hole up the center so
i could run tubing from the pump through it. the pump lifts the water up
into the bowl of the birdbath, it fills the bowl and runs off the sides,
adding sound and motion to the pond. it aerates the water for the fish and
brings nutrients up to the watercress that is growing in the bowl.
hopefully, the watercress roots help clean the water for the fish. at least,
that was the general idea...

Subject: Help request: Designing above ground indoor pond

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.
