Thank you Lars for the idea of heating fish water with compost.
Actually this would be in reach for us because we are ecoforesters
(anyone heard of that? Only take the trees Nature has naturally
selected out and leave the forest) and do our own value adding, ie
mill the logs into lumber ourselves and end up with sawdust as a side
product. Yes, I would appreciate the web site.
Best
Jean

Folks,
I'm ready to construct myself an aquaponic swimming pool in a four and a
half foot "concrete valley" at the end of my greenhouse's concreted area.
Where I want to place it, the concrete ends and then there is a nearly
five foot drop onto gravel, and then about five feet further is the
fenceline. The pool will be about 5ft by 20 feet.
I already have a polyethylene liner, but now I need to make up some
supports. It has to be non-permanent though (I might want to relocate in a
year or two), so I thought of using slatted pine to make the "cradle" for
the liner.. Either that or railway sleepers bolted together.
The pool will go above the concrete "abyss" :-) and will protrude about
2-3 feet above the concrete making about a seven foot deep pool. My
questions is:
* will the pine or the railway sleepers be able to hold
the weight of the sides
Does anybody have any experience in doing things like this?

I think it'd be pretty cool to go "diving" in your own pond to garden
lillipots underneath the water, skim filter the bottom, etc.. I can
imagine people's responses:
"I went diving today with the fishes to clean up the dam floor!"
"Where?"
"In my swimming pool"

Besides aquapondering, I grow blueberries for a living and use mountains
of sawdust each year as mulch. I currently have about 1,500 cu. yds
waiting to be spread. These piles heat up to an amazing degree without
any added nitrogen at all and, depending on the size of the pile, will
continue to produce heat for several months. I've always thought that,
if I ever expand my home-scale aquaponic greenhouse to a commercial
scale, it would be interesting to pile the fresh sawdust against the
north wall of a solar greenhouse for both insulation and a source of
heat. At the end of the heating season the sawdust would be spread on my
blueberry fields and the following fall a new batch brought in.
Developing an active system becomes a little more complicated because
tubes with circulating water, air, etc would need to be embedded in the
pile to capture the heat. Moving or working around these tubes with heavy
equipment becomes problematic.

Michael,
Depending upon the dimension of the lumber you should be able to use
pine but thicker is better, 'natch.
A 2x4 pushed against the 4 dimension is abous 16 times stronger than the
push against the 2 thickness so you may need more lumber but stacked on
the flat.
ie: this better for stacking ---- vs: l
l <-- this is good for joists
Also can you brace it?

Martha,
I am a non-aquaponics source, meaning I don't have the fish, etc, yet I
am learning from the group. Tell me why you gave it up as you gave some
great opinions yourself...

Don't get you. Would it be possible to send me a .bmp or a .gif. It
doesn't have to be pretty.. just something to illustrate this to me.
DM> Also can you brace it?
I certaintly can. I was thinking of something like this
oooooooooooooooooooooooooooooooooooooooooooooooooooooo
oooooooooooooooooooooooooooooooooooooooooooooooooooooo
oooooooooooooooooooooooooooooooooooooooooooooooooooooo
oooooooooooooooooooooooooooooooooooooooooooooooooooooo
With a big X type brace spanning it. Would this be sufficient. I think the
bulk of the weight would be on the bottom, right?

Michael,
In rereading your diagram, are the sidewalls supported by the earth? Ie
are they below grade?
If I am seeing several parallel wooden supports, describe them to me or
I may be missing something.

Okay, here goes:
The first foot of the pool is supported by earth (well, sand). This could
become two foot if the need arises. In fact, for illustrative purposes,
I'll say that the first two feet is supported by earth with the bottom
being sand to stop the liner from rupturing.
The longest actual "length" of the pool on one side (the 20ft stretch) is
supported by a concrete wall which is 4 and a half feet in height. This
gives the pool a total height of 6 1/2 feet. The next 1/2 feet is
supported by two large railway sleepers. When I say supported by concrete,
I mean that sleepers will be there as well, but the sleepers will "lean"
against the concrete for added support.
The other side which is 20 feet is by a very weak fence and will need to
be supported only by the sleepers around the sides.
One of the width (5 foot) sides closest to the fence has to be supported
only by the sleepers, and the other width side can be supported by bracing
of some sort.

I hope that wasn't a blunt way of saying that I don't have a chance :). I
went to the local pool store and saw an outdoor above-ground pool MADE OUT
OF ALUMNIUM. It was only about 5 foot deep, but it seems to me that my
sleeper pool would be stable enough??
