Heat pumps can be used to transfer heat from one location to another. You
can heat or cool water depending on how you set it up. You could pump heat
out of the air even on the coldest of days but it takes less energy to pump
the heat from a source that is constantly warm such as underground. Air
conditioners are heat pumps too.

Actually, I'm not really sure what 'apple snails' are, as i think that
term is used to describe a very large family of snails found worldwide. It's
what the people in the pet store call them, and you know how that is. Common
names and all. I think they are related. They won't eat live plants if they
are well fed with dead plants and/or vegetable scraps. Incredible creatures,
really. They have eyes! One's you can actually look at. Imagine a snail that
(at least seems) to look at you. Here's a good web site with more info.

Dave, this would be a change from the norm. Back before internet access
was cheap and plentiful, wordwrapped messages were NOT desireable
because most people signing on were not necessarily using an 80x25
terminal screen. In fact, most people don't today now that we are using
a GUI.
The idea is that the only time a hard CR/LF should be encoded in a
message is to terminate a paragraph. Otherwise, a paragraph would be
sent as one long unbroken line. It is then up to the mail client to
determine where to map the line breaks out. This makes the most sense
as everyone is going to want their line breaks at different places. I
keep my display at 1280x1024 and want my lines wider than someone who is
running 800x600 with "large fonts". My mail client handles this quite
well when a message comes in without the line breaks hard coded. Please
don't ruin that for me. Please just find the setting in your mail
client which will insert the line breaks when you are *reading*
messages. The others may be very well aware that they are doing this
and they are doing us a favor, believe it or not.

Robin & Mel - you've read Dr. Rakocy's comments. He's not kidding-the
wholesale market price has fallen big time. You can make money on Talapia
but the key is keep it small to start out and direct sales to a local
market. Also most of us (commerical fish farmers) use blowers not
compressors and surface areation such as agitators. Ken Hale

Some financial analysis of the type of system I run (which is different in
design from all others mentioned on this list, I think) is available in the
following doctoral dissertation by Richard Mark McMurtry: "Performance of an
Integrated Aquaculture-Olericulture System As Influenced by Componenet Ratio",
available from UMI Dissertation Services, 800-521-0600, Order #9023395. It is
obviously a research paper and the numbers are extrapolations but it is a source
of some hard data. I have not operated my system at the same stocking rates so I
can't confirm the information myself.
And welcome to the list.

Plants love humidity so I don't understand why you want to remove it.
To answer your question.
Create a cold surface area for the vapor to condense on.
A cold surface might be a water spray(fight water with water) or the cold
side of air conditioning coils. Water storage will also stabilize humidity
levels.

Hi jorg -
I don't know much about composting toilets. I've read about the clivus
and such, but they were so expensive i didn't even consider it. Have you
made one
yourself? Maybe you could describe it to me.
But i've noticed no problems with fauna and worm compost tea. Honestly,
however, I haven't had that much experience with fish. But I _strongly_ doubt it
would cause problems. Especially with your paradise fish, as they are labyrinth
fishes. For those of you who don't know, labyrinth fishes (gouramis are the most
well known of the suborder) can survive in water with almost no oxygen - due to
the labyrinth organ which functions kinda like a lung. In their natural habitat
they live in water which is stagnant and muddy for much of the year. I'm
going to
get some pearl gouramis once my tank settles in a bit more.
What are comets?
I'm surprised about the water hyacinth. It's usually barely
controllable.
My guess is not enough heat, light or maybe it doesn't like water thats moving
too fast. It _does_ like water with a lot of nutrients, which also improves it's
value as animal food..
Speaking of floating plants, have y'all visited the 'duckweed
clearinghouse'? :
http://www.prism-usa.org/
It's got _lots_ of info on duckweed. Like, for example, did you know that
duckweed grown in nutrient rich water can be like 45% protein? Sounds like an
awfully good free fishfood. My goldfish could never seem to get enough.
Does anybody know about tilapia, for example, and duckweed? Do they like
it?

Taro plants are indeed edible. They are the 'potato of the tropics', ie.
the main root crop and starch source for millions of people worldwide, but
especially in polynesia and melanesia. Pacific islanders brought them wherever
they colonized.
As with most plants that have had a long, domesticated relationship
with humans, there are many, many varieties. Orginally somewhat poisonous -
due to calcium oxalate, I believe - but I think most domesticated varieties
have only trace amounts of it. Anyway, calcium oxalate is either denatured or
removed when the root is cooked. I believe the stem is edible as well, as the
lady at the asian market who sold me the plants was trying to explain to me.
The root is supposed to be like potato but slimier. My plants are babies and I
haven't dug them up to see the tubers yet, nor have I tried eating them. Most
varieties grow in swampy lowland soil. It looks like (and might actually be
related to) "elephant ear plants".
Just a brief search on hotbot will reveal lots of sources about taro
culture, many of them from hawaii. Apple snails, by the way, LOVE taro. They
are a big pest in taro farms, but i think it depends on the variety of apple
snail, and how much other food they are fed. I give my snail the stems when i
cut off old leaves.

hi jorg -
oops - I didn't mean to suggest that adding worm compost tea would
_necessarily_ lower your oxygen levels, just that many of these fish
orginally come
from what aquarists call 'blackwater' environments. These are slow-moving
shallow
streams with lots of organic material. People often use peat-filtering to
simulate
this environment in fishtanks.
You could _potentially_ increase oxygen demand if the compost tea
were to
cause an algae bloom and then die-off, but it sounds like most of your
critters are
quite tolerant of that and you've got lots of aeration. Apple snails are a good
indicator of dissolved oxygen as they only bother to come to the surface to
breath
when the D.O. levels are low (they use their gill when DO levels are
sufficient). I
imagine labyrinth fishes would act in a similar fashion.
I think adding worm compost tea would probably make your paradise
fish feel
quite at home, actually. It will darken your water, but that's OK (though
you might
want to increase the light if you have immersed aquatic plants, as less
light will
filter through the darkened water column). Clown loaches and rasboras, for
example,
come from similar environments, and they are happiest in dark, tea-colored
water - it
helps them hide. I find the brown water quite attractive, myself, especially
when
it's lit at night.

thanks for the info bout comets.
duckweed does sound delicious but I. haven't tried it, yet. I dare you
first.
But seriously, people are starting to use it as a supplemental farm
animal feed, like for pigs.

Subject: greywater and soaps
From: jilli and lars
Date: Tue, 16 Feb 1999 15:48:56 -0800
This question is for jorg and any others who are doing greywater processing:
What sorts of materials are in your greywater? I imagine soaps would be
the main
thing. What sort of soaps do you use? Are there certain kinds which should
definitely be
avoided? For example, we use a biodegradable dishwashing soap ("planet"
brand) that
contains coconut oil based cleaners, sodium laureth sulphate and salt. The
warnings I
have recieved about sodium accumulation have made me think twice about using
this stuff.
I know that soaps and oils _do_ break down in my system, but I'm
curious about
the chemistry involved. Have you found any material relating to that?
thanks,
lars

hi jorg -
what are the ingredients?
How many gallons of soapy water do you add to your system every day?
Does your system handle all of your greywater, or is it a partial system?
thanks,
lars

Avoid those w/ borax!!!!! Necessary but only in very small
quantities.Prolly would OD after one wash.

I think my top 1 inch will be dry because the cut in half drum is 12
inches and will be filled to there with perlite. We've tested the
water being drained into the empty half drum and the water comes up
to only about 6". Do you think that's too shallow. My perlite
arrives Friday.

Dear Lars
Thank you.. I am not squeemish about worms. I have been collecting
worms as of late, as I transplant trees, ect, to an abandoned
pasture I'm trying to restore back to it's natural forest state. I
hope regular old wild native worms are the right kind? Then I am
going to make a worm castings bin what'cha'ma'callit as suggested in
greenhouse books I've been reading. There's a drain on the bottom.
Yeh, I don't want to stay with the chemicals. I just want to get
started as the photo period is almost long enough to grow things
again. And when my worms get going I will be switching over. Thank
you and everyone on the list for the great concern for ecological
sustainability and sensitivity.
Jean

These are the URL's for greywater I have at this time:

This forum might help:
http://www.europa.com/~aball/msgs.html#post
Please note that when searching for such, there are 4 spellings:
greywater, graywater, grey water and gray water.
I would be interested in other sites especially where greywater can be
used for growing purposes or at least how to minimize what can be dumped
into water safely then reused.
I make my own soap using various oils and and lye and I am looking to
collect wood ash to make my own potassium lye solution. The residue in
greywater would be safer for garden use. I'm not sure how it would
affect an aquaponic or hydroponic system but I would believe it would
break down safer with less salts or other residues.
I welcome the group's collective thoughts.

Hello Jean,
As long as the water level in the perlite just covers the roots you'll be
okay. You could poke your finger down into the perlite and test to ensure it
is. If not, add more solution to the drain bucket. Do you plan to raise and
lower the drain bucket manually all day? If so maybe you'd consider switching
to a passive wick system where the solution pulls it's self up into the plant
root area. You just need to top off the solution tank once in a while
(weekly).
Have fun,
Joel

Lars: Our hydroponics, marshes and fish tanks get some or all of the
soapy greywater. "Nature Clean" is 100% pure castile soap without
phosphates, animal tallow, dyes or perfumes. Its ingredients are water
and potassium soap (from several vegetable sources). It is biodegradable,
non toxic, hypoallergenic, septic safe and cruelty-free. That is what the
bottle says. The company has been around for 30 years, I think. Two
people use 11 litres of water per day. Our GreyWater GardenWall is a very
small solar aquatic system meant to handle 200 l/day. Our planter boxes
with subirrigation serve as option number 2. Two slow sand filters did not
work out very well, and I would like to convert them into a
vermicomposting/sand/activated charcoal greywater filter if it gets
designed (perhaps as a group effort on this listserver?) and built.

The tomatoes in my room are in three inches of perlite. The roots are a
little matted, but other than that I have had extreemly good growth from
them and 100s of tomatoes.
Footnote #1 has a great address for perlite information. Its quite
interesting.. they claim that plants grown in perlite grow much better,
healthier and faster.. I don't know whether the claims are bogus or not.
