The fish look like thay are being eaten, usually at tail, anus or fin but it
can be anywhere. The temperature varies between 26-28degrees centigrade. The
only recent changes are 1/a change in food from fish meal to broiler chicken
feed about 3 weeks ago.2/increase of B fertilizer levels from .2 to .5 salt
levels. The only unusuall things about ourt setup is a ph of 6.8 to 7 & our
Amonia to Nitrate bactiria have rarely fired.
It has been suggested to us that we may have "Fluke" whatever that is & that we
can get rid of them(along with thousands of snails) with a "pinch" of some
crystals(I have got the name somewhere and they're chemical composion).
We will vacumme the bottom of the tank & change most of the water.
Any more info u require & thanks very much for replying

Howdy, Tony
I don't have an aquaponics system, and have never raised fish,,, that
said,
Your problem brings to mind a product that I am aware of that might be
of some help.
It is called "grapefruitseed extract"
SO far on this list I havent got anyone( it seems) to respond to this
tidbit of information.
It is antifungal, bacterial,viral, and can help out when parasites are a
problem.
ALong w/ all the other great advice on the list( water changes, tank
cleaning, etc,
you might investigate it's uses.
Any search engine ought to help you link up, ( as can any local
healthfood store).
The vendors of same have stated that it"grapefruitseed extract"
functions as an fishtank algaecide, and seems to help w/ the health of
the fish as well ( at low doses 50-200 ppm).
I have stated that I don't know the consequencse of using same when
it comes to preserving the flora in the gravel beds of these systems.
Maybe the low doses are of no consequence, maybe not., but it seems that
there is something here of value.
I realize that there might be readily available products available for
just waht ails your fish,
but, this stuff is made from grapefruit!..and it works for me( colds,
sniffles, athlets's foot, cuts, infections, and more.

Thanks for the replies.
Bruce
The GARF site makes the construction look pretty easy. I figure the cost at
less than $200US for a 700 gal unit(8'x4'x3').Not bad.I may have to give this
a shot in the near future.

It would seem that the angle iron may be unnecesary, although it may be
priceless in the "piece of mind" department
J Allen
I have been considering the "pond liner" approach and this method is still in
the realm of possibility.This only real drawback in my opinion is plumbing.I
favor the idea of thru-tank plumbing where as using a liner would seem to
require that all piping be run over the top edge.Still looking into it...
all for now

Subject: Hyacinth Leaf burn
From: dreadlox 'at' cwjamaica.com

Wow..some of the stuff I have seen on the last few weeks here is
PHENOMENAL.. Glad to see everyone fired up and spunky. I had a look at
that site Neal re the feedlots and its something similar to what I have
trie dbut only with human waste.. in remote situations and sites.
I have built a pilot site using hyacinths as the polishers.. now here
comes the "clue"..
The system works liek this.. Seperation Stage... filtration..
biofiltration , UV treatment, discharge and flow spitting back to
seperation stage respectively..
There are 5 growbed stages after the biofilters..
After I left the system in the care of the folks in this remote
location, they apparently didnt pass the word around and turned back on
the chlorine disinfection at the last stage, as opposed to my UV light..
I came back to see the leaves browning.. like someone had passed a
blowtorch over them..
Since then I have checked the pH and its now back at 7.3 which is good..
(did so within a day..) and within environmental folks demands... but I
have noticed this leaf burn in my tanks which wasnt there in the
beginning has remained since then.. and the strange or obvious thing is
that the "burn" seems to be worse in the tanks nearer the biofilter
outlet.
I was wondering Ted (man some of those sites U send are
PHENOMENAL...!!and hey seems like our "agendas" are real close..I was
wondering if U got a copy of my business plan...hehehe. Was surprised to
see Ure experience re water hyacinth ) or Neal, re the feedlot sites.
I wonder if anyone has experiences as to how fast the hyacinth restores
itself..the growbeds look kinda shabby!!
Can a lack of excess of some trace minerals cause this?? I will run
nitrate and phosphate tests this week.. These are the last biggies and
will make or break my system. 9 out 11 "bad" parameters are now good.
I just need to know if I should chuck these plants and get new ones or
just give them time to stabilize..Is the leaf burn some indication
already of high nitrates?? I think not but...
Help anyone?
Kind regards.. Mike

Hyacinths double in size about every 14 days in nature. So I would think if
your plants were going to come around that they would already have done it.
It could be that the biofilter is part of the problem. Is there excess heat
or chemical contamination of the exhaust?
Do you use the hyacinths for any feed or energy production?
