Anyone have a suggestion for an alternative treatment for this operation?

Are you sure that your Hyacinths have leaf burn from the sun or do they
have a leaf maggot infestation? If your Hyacinths came from a hot house
in the north with artificial lights they will burn for a time when
placed under hot sun light but soon regenerate new leafs as they do best
in the tropics. But if you have a maggot infestation its caused by a
small tan moth about 1/4 inch in size they must be treated with the
(Bacillus thueriences spores) spelling? available at garden centers for
grub and caterpillar damage to recover and this stuff works excellent.

You can still go through the walls with any liners just go to a boat or
yacht shop and get bulk head fittings in the size that you want drill
your holes and pop in the fittings they self seal with O rings .
I hope some of you explored the GARF site its a great DUI how to
site for for coral farms and marsh experimenters they tell all and for
free

Hi Brian,
I've done some work customizing cars with fiberglass and recommend using
epoxy saturated nylon rope to filet the corners, than add a layer of cloth
tape. Fast, strong, and easy. Put rope in plastic bag, pour in resin, mix,
and use.

Subject: Channel vs bed
From: "Tony Cooper"

I have been running a (non commercial) aquaponic system for about a year
now, using fiberglass channels approx 5" wide 4"deep and 24 ft long.
I haven't tried the conventional S&S type bed so would be interested to hear
from anyone who has operated both channel and bed, what they feel are the
pro's and con's.
My observation is that channels give complete irrigation with no dry spots
that i have seen in some beds, and even with the 24ft length the plants
furthest from the water supply seem to be well nourished. I am using
calcined ash from burnt sugar cane screened to 1/4 to1/2" instead of gravel
as it is much lighter and is very porous, it has held up well over a year
without significant breakdown.
I have had success and with most all vegetables i have tried except for
lettuce which will not form good heads even the tropical varieties that were
recommended to give good heads ahem. Here in the Philippines lettuce is
grown at cooler altitudes or in climate controlled hydroponic systems.

For those of you designing plywood tanks- remember that a gallon of water
weighs about 8 pound- 700 gallons weighs 5600 pounds- the joints and through
wall fittings for these tanks have to be designed for that pressure. The
angle iron in the corners is a great idea- athe more screws holding it
together the better.
We built the outside tanks for solar aquatic systems in the Northeast.

Tony,
Are your channel bottoms horizontal or do the have a slope, if so what slope? I
would also like to know how you water the channels, only at the beginning or are
there several inputs. Finally, what plants have you grown successfully in only
4" deep beds?

Tony Kill off the snails and fluke (flatworm)
ether could be an intermediate host for this thing that your fish have
.Also be
careful with putting your bare skin in contact with the water of the
fish tank if you have any cuts on your self !!!.
Especially If the fish look like they have tiny chunks that have
been torn out of the body and the wound edges are bloody because the
fish can have open Tuberculosis( a nasty skin infection in humans and
hard to treat 6 months minimum)
It would help if i had a picture.
If the skin clouds up in some areas,then comes off,leaving bloody
patches its a heavy Costia infection so increase the water temp. to over
30 C,then treat immediately with SALT (kitchen,Rock,mineral,or sea
salt)about 1 teaspoon to the gallon or about 25 lbs? to 1000
gallons.What is your system size? For five days than reduce salt content
by changing the water or you can use Copper sulfate(blue crystals)but I
am not sure of the dose note( both remedys are toxic to vegetables )
If you go on line check and see if you have a fish hatchery close enough
to drive to and bring a few fish for examination.
In the future set yourself up a small lab.with at least a cheap
microscope available at a hobby shop and from an Aquarium book store get
Handbook of fish Diseases its always been helpful to me

... if the system splashes the plants, you ask for it...
,.. air circulation is important for health...intensive plantings can
bring on "leaf spot"...
,.. cool/moist air temps=>leafspot is more trouble
,..remove affected plants( or leaves, if you've the patience).
,.. get rid of nearby weed hosts: horse nettle, morningglory,jimsonweed
Afteer reading up on this , I realize I've "it" as well.

Hey Steve in the last week i was sent 2 bombs but this webTV caught them
which is why I wont use my computer for email. They were email
atachments and were untiteled and must have come from the aquaponicr ,
tilapia or redclaw lists however I get 50 emails from this list for
every one from the others so it looks like we have a mole playing around

Interesting point Bruce...
Now that U say it, Im not sure what leaf maggots are, but the leaves
have also simultaneously been taken over by a lot of black tiny fly
looking insects near to the bulb bases.
Can someone tell me more on these leaf maggots? The leaves did have some
black streaks in them when I took them from the natural river they where
in...can it be they were infested from then??
Regards,
Mike.

Is there a way to make drinking quality water out of river water, for
example, without using electricity? I would like to avoid chemicals also and
only use filtration or some process which can be powered with natural gas or
methane. I think that evaporation would be too inefficient though.

Neal Van Milligen,
When you start getting into a filtration system for river water you are
entering a gigantic operation. Do you know the content of the water? What
chemicals, disolved solids and other substances are in the water?
Without expensive testing the best process would be distilation.
There are some good filtration systems on the market but they are designed
for household use with a controlled amount of substances.
I would also like to know if anyone had found a good system. My water here
in Albany contains 388 particles of disolved solids. I pass this through a
Brita and it is reduced by approximately 90 particles. I have been thinking
of adding another Brita in tandom to see if I can get down even more. Maybe
in the next few weeks.
