    Fellow AquaFolks :)

    My name is Robbert, they nick me as Berto.
    I live in a small country in Europe called the Netherlands (Holland) and since 2010 I came across the line of Aquaponics. Together with brother and friends we kept that same line.
    After reading 'n studying about the system and it's idea we started in the winter of 2012 transforming the garden and making it ready for aquaphonics on a small scale ofcourse.

    In the same time I was given the opportunity to see Murray Hallam's Aquaponics movies.
    We studied them a lot and wish to give our gratitude!
    We were so enthousiastic about the whole idea but had to stay focussed on the fact that here in our lower lands we deal with a wet-maritime climate, not the one most of us here is dealing with I understand.

    Anyway because of the abundant rain and possible heavy winters (2009-2011 was minus 20) we chose for an indoor system with IBC's.
    P1012077.JPG
    Spring 2013, we have the IBC halfway sunk in the ground.

    Now we wanted to start as quick as possible with some growbeds and a floating raft,

    P1012208.JPG

    Couple of months later we have a second (claypebbles) and third (gravel) growbed realised.

    P1012288.JPG

    In the above picture it is about summer. We started the first seedlings in our growbed near the end of March.

    P1012300.JPG

    We tried to grow Courgette but it seemed to work only for the growing-phase of the plant.
    As soon as the flower started to appear, all of the plants showed weakness.
    The fruit it tried to grow immediatly started to rot.

    P1012302.JPG

    So we decided that before we see the first flower, the plant goes outside in the sand-bed.
    This one over here bore fruit!!!

    Now this is my moment (for the moment).
    I'd like to share all last summer up to now with all of you guys!
    But you do understand it will take time.
    Let me end with this picture of the last Courgette from the plant mentioned above. (oktober 2013)

    Have a nice meal / Eet smakelijk!

    Hi Silloth,
    Yes we like the setup as well.
    We have some Goldfish and related fish like Sarasa. Total is around the 20.
    We chose these because we were going into our first winter and were not sure how cold it was going to be.
    As we are in the spring now, we only had 1 daytime minus zero. Huge difference in our world climate!

    In the moment we are about to put more fish in the tank.

    A question:
    Can I put Tilapia in the same tank with the Goldfish? Anyone has experience with this?

    Another question:

    On this moment we have not so many fish and 3 growbeds plus 2 floatingbeds constantly flushing into the fishtank. Do we need extra aeriation in the floating beds for the roots ?

    I noticed that the Kh doesn't come higher then 5, most of the time its 4...

    I read somewhere that putting too much oxygen in the water aint good for reaching a Kh 6-10.

    Any comment or answer is welcome.

    Thank you all!

    Allright going nuts..
    Some more great results and against all odds these crops came from one of the first harvests.

    DSC00938.jpg

    DSC00939.jpg

    Unfortunately around the time we added the gravel growbed, we had some strugglings with the values. Result was 50% loss of fish. The plants in the growbed did well though. End 2013 we disconnected the gravelbed and replaced it with a real IBC format with clay pebbles.
    Luckily enough we found some other seedling in our garden outside the greenhouse:

    DSC00941.jpg

    Well aint that a wise thing to do!

    Still can someone help me with these quotes?

    hi bertos
    no experience with talapia but i am guessing not especially when they get a bit of size
    about them
    i would have thought trout would be a perfect fish in your climate fast growing
    and a fun fish feeding time
    you can never have enough air more is better,have never taken DO readings (disolved oxygen)
    the only readings i take are for
    PH, NH3, N03, N02

    Update:

    We put the aeration level on maximum. We checked some roots while ago, they look fine to me!

    DSC01273.jpg

    Now we've put the reinforcements in place.
    Beans & peas!

    DSC01288.jpg

    For the beans we chose a special mini-growbed.
    The syphon has a diameter of 20 mm. Bed is 250 mm with pebbles.

    DSC01286.jpg

    Also placed the 3rd growbed in march this year, for protection against algue a black one.

    DSC01259.jpg

    Some 5 days later we had the bed as following.
    We always love to have as much diversity as possible.
    A bananaplant in the middle with little peppers behind at the window(sun)side together with a mini-cumcumbre. Next to the banana an oak! On the right some red cabbage & black mustard germinating seeds. Just inside the picture we see a blackberry, does anyone have a comment or suggestion about this? We had lots of little bastards on the leaves who started to eat & creating holes in the green. Manually removed them, very tiny caterpillars or silkworms or something like that. We cut the damaged leaves as well and we'll see what happens. If anything happens again we will see a sign of black spots which I assume is the poe of those bastards! That's what made me search for them in the first place.

    DSC01285.jpg

    Below our first growbed, it's over a year old now and seems to have matured.
    All the plants in this one do very well! Especially the Portuguese Couve!

    DSC01246.jpg

    DSC01282.jpg

    Last one the tomatoplant who survived last winter. The thing has gone wild but we'll try to get a hold of it. It's shows the first signs of productivity as we speak.

    Cheers Murray,
    Indeed we got rid of the bugs, the ones who were pigheaded.
    We still check if any holes in the leaves appear.
    For the moment it is allright. The bugs stay outside but we open the door & windows
    more often because of the heat. Any good bugs are welcome ofcourse & for the bad ones we have hidden webs. We have coldwaterfish and the climate changes, so we even need to think about cooling down the temperature of the fishtank.
    The Koi we also added is our main target to keep focused on.
    The water cannot exceed 29C/85F and may not drop below 16C/35F.
    Temps are fine though!

    Here a guide of our little greenhouse, end of april:



    As we speak we have put new seedlings to grow for we had some changes in our plant system.
    The sprouts have been removed. It takes a lot of time to have them ready for harvest and the leaves were blocking all sunlight for the surrounding. We have harvested loads of lettuce, cucumber, couve and portuguese couve from winter up to middle spring. Now the focus comes to our seedlings some other plants and ofcourse the replacements for the lettuce etcetera.

    Hello Folks,

    Again this forum and it's knowledge is just brilliant!
    As in the movie just one post above, you see a mint (Mentha) plant just in the last second of it.
    Well someone around here mentioned the Mint Monster!
    I directed myself in the greenhouse for a check; and yes the runners or so called fingers were present!
    The mintmonster has running fingers! Going everywhere in the growbed!
    We decided to put the plant apart but still inside the house.

    Here some pictures of may 2014:

    P1012632.jpg

    P1012624.jpg

    P1012642.jpg

    Our mini-cucumber plant doing very well

    P1012643.jpg

    And some more veggies coming up!

    P1012649.jpg
    beans
    P1012650.jpg
    mini-tomatos
    P1012651.jpg
    peppers
    P1012658.jpg

    All sorts of green, we support a diversity of plants in our growbeds.
    Looks all brilliant and it ofcourse is! But as anyone else there are some minor problems.
    F.e. the strawberries leaves all turn reddish to brown till it dies. Dont know why this happens.
    The plants do create fruits though but not many.

    P1012657.jpg

    Any help or advice is welcome!

    Had to stick this here, thanks

    Too much DO is toxic to plants in DWC. A DO meter is a must to find the optimum level in any system to achieve the best results.

    The water will only carry as much DO as it can. Usually not much more than around 5.5 - 6.0 in most well aerated systems. Plants require a minimum of 2.5 to do OK but do much better if it is higher.
    To achieve higher saturations some excessive methodologies would be needed such as very elaborate aeration techniques or direct injection of oxygen. DO saturation is also a function of temperature.

    Thank you all there; and keep up the good going!

    Update Octobre 2014:

    Went for a test-kit to measure the DO: somewhere between 4 & 4,2 is what we read. Not bad but it fluctuates.
    Also measured the Fe & PO4: they are just fine.
    One thing that worries me is the NO3, last time in August it was: 40-50.
    This could be because we removed some plants from our system? The advise on the label said we needed more fast growing plants, so we did.
    Going to check again this afternoon. Here our current setup:
    P1012684.JPG
    Some basil, tomatos and a coffee-plant (ever wonder how this one will do in our system) in GB1.

    P1012675.JPG
    Below the (mini)cucumbre, going really good, 1 plant has the counter on 40 and even going for more!
    P1012685.JPG
    Below the view from outside. Front below our courgette again, we put the seedling in the growbed and after a while
    (when the flower started to appear) outside in the garden. Just behind it a grape plant to have some fruit next spring.
    P1012692.JPG

    The system is really good and great great results!!

    P1012687.JPG

    This one tasted so well!

    P1012862.JPG
    Kilo's of fresh fruit & veggies we have consumed!

    Fellow Aquafarmers; update 2015

    Here some pictures of end last year:
    P1012897.JPG

    P1012868.JPG

    P1012886.JPG

    P1012864.JPG

    P1012895.JPG

    P1012885.JPG

    As we had the winter coming up, I decided to bring in a potbelly stove:

    P1012903.JPG

    For some reasons ofcourse.
    Like the last years one couldnot predict the winter outcome, so we take no risk.
    The tempuratures need to be constant and above 20 celcius at all times.
    What we noticed (reported earlier this topic) is we had a raise of nitrate levels.
    And that is important because the changes also have it's cause.

    In aftersummer, here in Holland, less sunlight is exposed to the plants and so
    the plants take less nitrate from the systems. Plus the time some plants are just finished,
    so they have to be removed/replaced at a certain time (end aftersummer, like oct/nov).

    Just removing them is one thing, replacing them and keeping the nitrate consumed is another.

    At that certain moment we just only took some finished tomato & cucumbre plants from the system.
    In a week or so the nitrate levels we measured were +100 mg/l; after that checked NO2 but that was 0.
    In any case we decided to almost completely stop feeding the fish and arrangend some additional bananaplants for the system.

    Meanwhile making a plan for an extra filterbox:

    P1012926.JPG

    Here you see some lime stone stuff on the bottom to raise the ph a bit.
    Long time was steady at 6, when it dropped I Immediately added them

    So we cleaned up the place starting a fresh 2015.
    P1012867.JPG

    Changed the layout and added a second minigrowbed:

    In this moment we are busy with a extra fishtank for trout.
    Measurements are like Height600 Width500 Length1500, has anyone any comments or tips on this?
    We want to have platesize fish end of the year.

    Busy with new plants & seedlings, added a citronella tree:
    P1012937.JPG

    More soon..

    More photo's as promised; end February

    Some of our changes in the layout.
    P1012946.JPG
    Minigrowbed; doing above expectations (we added more claypebbles)

    P1012953.JPG
    P1012948.JPG
    The fishtank, half submerged in the ground.
    Mostly Goldfish & Koi.
    P1012947.JPG
    More space available then before..
    P1012950.JPG
    The floating raft, doing very well with Winter Endive & Lettuce.
    Also Thymus Vulgaris works fine in a water-rich environment.
    P1012965.JPG
    February showed us some sunlight, together with the potbelly stove we created a fine biosphere for the plants & fish.
    Really love the smell like sub-tropical.. while outside it is 5-10 celcius, inside it's 15-25 celcius.
    P1012957.JPG
    One of my favourite beans: French Saxa or Dwarf beans.
    Doing very will in early season, as the label said.
    P1012962.JPG
    Dill.
    P1012963.JPG
    Green Chard.
    P1012966.JPG

    Let us welcome the Spring
    Let us be the Spring..
