We are in the middle of nowhere so we order from Grainger on line at
www.grainger.com   look at the hydronic section and under HVAC controls
in the line voltage and remote bulb heading page 3335 of cat. 391.

It is very simple to mix the high heat boiler water with water returning
from the exchanger / loop using of the shelf hydronic parts.It is called
water tempering valve system.  The poly is never over heated and you are
working with safer temperatures in the tanks. You determine
how fast you bring the water up to operating temperature and the operating
temperature range of the tanks. You can go low voltage but it is a little
more cost and a little more complicated.

Hi all:

I've done some pretty design work in Word Format I could send attached to
does willing. I feel proud for the simplicity but I would like (need) your
input in terms of viabillity. 
It uses only one pump both for oxygen and growbeds. Tank and growbeds are
send hand bathtubs. Greenhouse has not been designed yet.

It is a small project thought for low budget (South America). That is
relativelly Hi costs for industrialized input versus low prices for produce
in an overtaxed economy.

Thanks
Pablo

Thanks for the link, Devon. I have done something very similar with a 
90 gal tank in my living room.  I removed the glass tops. Found some
scrap acrylic at work and cut it to fit. Then cut holes for 3 in. net 
pots.  I had to make a light that I could adjust and suspend from the 
ceiling.  I could have done better here with some of the reflectors
that are available now, but the four 48" daylight tubes seem to be doing
the job.  I wired two rotary switches in to be able to shut off 2 tubes
if I am in the room and want softer lighting.  I was wondering if my
4 marineland biowheels would be enough biofiltration...so far so good
but I just have 2 dozen hybrid bluegill fingerlings in the tank.  It was
a fun project that I get a lot of enjoyment out of and hope to put in
a local pet store soon.

have a great weekend everyone...

Welcome christopher...there are no dumb questions here :).

The friendly bacteria are attached to surfaces...gravel, rotating 
contactors or whatever.  With UV, the water is passing through it as
part of the recirculating system so the bacteria in the filter medium
isn't harmed in any way because it isn't exposed to the lamp.  The 
good bacteria are also aerobic...they need oxygen. If ozone levels were 
extremely high, you may get a high enough residual after dosing to kill 
the bacteria...but at proper dosing levels this doesn't happen.  
Ozone is 03 where as oxygen is O2.  It is very unstable...
that is how it works...the 3rd oxygen atom breaks off and "oxidizes"
or burns up the bad organisms (and other substances). You then have 
O2 left...oxygen...which is beneficial for both fish and the good bacteria.
Any excess ozone breaks down very rapidly.  The thing that makes ozone 
popular in wastewater treatment is that besides sterilization, it has the
ability to breakdown many complex impurities as well...without producing
toxic byproducts (as chlorine produces trihalomethanes when exposed
to organic compounds...humic acids, etc.).  

This is sort of a simple answer but I hope it helps.

Subject: Re: VEGGIE AND PRODUCE FEED
From:    Arlus Farnsworth 
Date:    Fri, 19 Oct 2001 12:24:22 -0700

Here is a recipe I use, found on an aquaria message board:
corn and pea baby food
shrimp
spirulina
unflavored gelatin, partial strength (use less than full ratio listed on
box)
optional food coloring (some fish take certain colored foods more
readily)
These ingredients are expensive, but the formula could be made with
suitable bulk substitutes. Whip the mixture well to introduce air so it
will float. I layer the mixture 1/8 to 1/4 inch, depending on mouth size
and freeze it in sheets. I cube the food with a knife before feeding so
the less aggressive fish get a chance to fill up, but then I only have a
few fish (so far...) and I used to prep food at one time, so I am quick
with the knife and don't experience finger slicing anymore. For larger
scale maybe some sort of wire cheese type of cutter would be required.
The fish I feed are not vegetarian, and would not normally take a chunk
of food that was all veggie. They might nibble on aquatic vegetation,
but leafy vegetable would spoil before they got around to it.
Very young fish might require live food, egg yolk, decapsulated brine
shrimp egg, bring shrimp nauplii, microworms or other tiny aquatic
creatures.

What do you feed your smallest tilapia fry? Is there any variation to
your feed method of blending into half pea sized chunks and freezing in
mini ice cube trays (5% protein)? I seem to remember you said one male
and 3-6 female tilapia are moved to a breeding tank with hiding tubes
for the females and two caves (flowerpots) at either end for nests.

------------------------------------------------------------------------
The females carrying live fry/larvae get moved to an isolation nursery
tank.  If I move them too early, while in the egg state, the female
drops the eggs and doesn't always pick them all back up.  If I move them
too late, she releases the live free swimming fry into the breeding tank
and it's a royal pain to catch them all and move them.

For the first day or so (assuming I've timed it properly) the free
swimming fry are consuming the rest of the egg sack and don't require
additional food.  When they do start eating, they require microscopic
live food and I make a special recipe for the swim-up stage. 

Fresh hatched brine shrimp blended with powdered spirulina, powdered
zooplankton and blood worms.  I blend this type of food til liquid and
freeze.  

I've read that fry require about 95% protein and that the protein
requirements lesson as the fish ages.. so I have four different diets
depending on the age of the fish being fed with my oldest growout fish
getting about 5% protein from non-plant sources. 

The one exception is the breeding colonies.  I've found they produce
better on a high protein diet containing occasional whole bloodworms. 

Please remember that I am still a novice at all this.  I've been doing
the fish portion of aquaponics for about a year now.  All I can tell you
is what has worked for me.  I, currently have more tilapia than my
family can eat and more fry than I have room to move to a growout tank
but that may very well be a fluke, as I've heard many many folks say not
to bother with breeding colonies and I certainly think it is the more
expensive route to go.

I have never done business with Ken, only a few recommendations. He has
a website to get information, that is the difference. His business is
easier to find. Many providers or hosts will try to charge extra for a
business web page, but if you are only presenting a few pages of
information, no online orders and only a few people a day actually look
at your web page, there is not a distinction between a personal page and
what you have in terms of cost for the providor, I would try to avoid
that fee. You can get free web pages from many sources, but they will
put a banner advertisement on your page.
Good point about local stock being more aclimitized to the local
conditions.

Yeah, the bacteria need a medium to grow on... to convert excreted
ammonia and solid waste components into nitrite and then nitrate.

The xenon excimer bulbs are not as efficient as specialized florescent technology, but do not contain any mercury, have very even (flat) illumination, are brighter and last longer. I don't see why it cannot be utilized directly on the water... but then I'm not qualified to make that determination.

I have reworked my plumbing and made changes for better reliability. I have changed my pumps if when the model I was useing proved unreliable. the last time I worked on my south sump pump I failed to make sure it was resting flat on the curbstone in the bottom of the sump. A small mouse got in that sump and pluged the pump intake, dead fish galore. If the pump had been flat on the cement under it the. mouse could not have plugged the intake. But if my suction pipe in the fish tank would have had a couple little 3/16 inch holes about a foot off the bottom the suction pump would have lost its prime and I would have been inconvenienced but not dead fish. I've tried lolevel shut off switches and the shut down just for the fun of it. Well the pacu are in the freezer. They were 3 inch fingerlings 90 day ago. They weren't a uniform size and I don't have a scale but they where 5 to 6 and half inches long and from 1 to two pounds in weight. thats impressive to me in 90 days. This is not meant to discouage any one. I get discouaged and down for no reason at all but in the face of real setbacks I laugh. I like these pacu and think they have great promise. I have some questions I'll be asking as soon as I'm sure I reaaly understand the question. Chris Jeppesen
