my pilot project francois

Recommended Posts

R1 and R2 refer to revisions.

1)R1 growing trays (wide)

2)pump/duckweed

3)dam/fish/tilapia

4)R2 growing trays (narrow more manageable)

my dam i have also had to half in volume to be able to do most

of work myself.(more manageable)

(was 22000 l water now max 10000l water)

my system = dam - gravity - into grow/tray's - into duckweed - into sump -

where the level is controlled - water pumped through a swimming pool filter with sand back into the dam.

in my growing trays i have +-25 mm stones.

i started of with smaller stones. (did not work well)

in the growing trays i also have worms.

i have been growing all sort's in my growing trays.

it works very well.

hi all

THANK you very much.

a lot of hard work.

i designed and build my own system.

started of with the basics

and doing upgrades to the system going along as required.

i want the system to run itself.

problem free

i have a full time job (my own boss) but still have to put bread on the table so my time is restricted, this is just a hobby.

me myself (plumber/sparky/-----from a to z)

i do all that is required to keep my project going.

quiet a hand full.

i call it walking the road.(apprenticeship)

learning from your mistakes in practice/reality and going forward.

improving and trying thing's making your system better and learning the ART of aquaponics

yes ravnis it is a hydrex wire mesh dam and tilapia liner.

photos

before and after the wind

lots of back breaking work gone in a second

but we will carry on

once the bug have bitten no return

thanks again

morning gary

basicly my plastic tunnel framework and some plants

broke my spirit for about 4 weeks (basicly just leaving the system to run)

plastic not much of concern now summer

my temp. is +- 5 degree's lower with plastic gone

my mor.temp.+- 20deg afternoon +-30 deg.

more manageable

my system runs very well with little hickups

There appears to be 2 systems in the pics one with the black tank feeding into a raft system and a grey tank feed into the troughs filled with rocks. Very interested in construction methods on black tank with wire and liner. Is the final tank downstream from the black tank primarly a sump or does it also have a filtering function. Looks very impressive.

Hi Francois,

I think Moose is reflecting the interest of others of us. Can you post a diagram which shows how each of the elements is hooked into the system?

I love what you've done with the low tech grow beds.

I think I got it the grey tank (dam) is the black tank (dam) reduced in height and the liner rolled down. What is the round structure in the tank (dam)

yes moose

what you see is right,the dam i cut down in hight and rolled the dam/side over the wire mesh.

the dam was 23 000 l now 11 500 l

i manage/run the sytem on my own, one man operation.

i spend minimum time on maintanance/and the running of system.

the final tank downstream from the black tank is sump/filtering filled with duckweed.

the round structure in the tank (dam) is a grow out tank flouting in the dam.

i keep all my tilapia fry in this flouting dam.

2/3 months then you can sort males from females.

i have been trying to get to the stage were you have only faster growing males in the system.

i think it works well.

due to water quotas of 500 L per household per day i am forced to stop my project.

very sad/ this is my passion.

i am in the process of selling all my fish and breaking down the system.

my system is on rented property.

gary i will send a detailed layout of my system as is,

and with my vision of what could improve my system.

Is there no way to keep it going. Where are you? Would like more info on how you built the tank. I have seen pics of similsr but they all had post around the pirimater.

i live in port elizabeth south africa

at the moment we are in a severe drought/worst recorded

to keep it going -------

traveling to where my system is every day, there and back i have lost 2 hrs in that day

time and water are my concerns.

my tank if refering to the duckweed tank is made of 2 mm plastic 6x30 meter roll i cut and folded

i do have a Ø40 mm pvc pipe knocked into the ground to support the sides.+- 1.5 meters appart.

will start up again when more organized.

i want to do this in a big scale

i have been going to school (trial and error) with subject over the last +- years (learning the do's and the dont's of aquaponics.)

from day 1 i have been on my own with this and the bigger system tought me allot.

i feel comfortable with the idea of - max fish- min water and feading max what fish want to eat.

i want to be one of the few in this country who do this on a bigger scale

you can't believe how many people i speack to, that have not ever heard of aquaponics.

here in this country very few people know aquaponics.

its my love and passion.

My interest is the large tank and liner

the dam is a tilapia 23 000 liter mesh reservoir from hydrex a company that produce them in kit form.

the black side you see is before i cut the mesh side down to halh the hight.

i then rolled the dam liner(grey) down on the outside.

i did not attach the file of my top view earlier.

let me try again.

hi moose

good idea make all your cages round and floating

center outlet with water rotating with inflow/

water moving all the time/oxygen

keeps dam clean/

just my thought

good luck
