Gaetan Dureau - Aquaponics

Received few photos from Mr Gaetan Dureau on his aquaponics set in a small village located  North Eastern part of Thailand near city of Khon Kaen ,its interesting  to see how it was all constructed and put together.


I do not have much information on how all was done and as he mentioned its still newly build and still cycling.


Here are some of the photos.


Just a note from what I could deduce, those cement will make Alkalinity shoot up,  plus limestone use as growth media will cause water PH value sky-high, just ensure this set is cycled properly before putting fish or plant.


I recommend pineapples peeling or vinegar or lemon be added to water in tank for about a week to bring the PH to below 7.5.

  1. Might want to try painting all cement surfaces with rubber or two part epoxy paint. Not sure if it is available or cost effective in your area. But it would stop the leaching.

  2. Affnan, what is the difference in the material he used for his tank and the concrete you used for your tank? Do the blocks have more alkalinity than concrete?

    I am curious because I have contemplated building aquaculture tanks for a RAS system for catfish in the past.

    I have seen a water sealant paint in the hardware store. Could a sealant be used? I guess that may eventually leach in to the water maybe.

    Same material as I use, except his concrete block is of the bigger type mine is the concrete brick. Tank wall plastered so that its water proof.

    Cement tank will have high alkalinity, having said that I do have high alkaline in my set but it stabilized at 7.5, to make it lower just add some vinegar or lime juice or pineapple cuttings.

    I let rain water pour in freely in my setup, they are acidic so, will help a bit in controlling alkaline.

    I don't see any problem with using concrete tank in Aquaponics.

  4. Affnan, I found a product that may be of interest to some who would want to build concrete tanks. It is a rubberized epoxy paint that is made to seal outdoor ponds or tanks.

    The product is called Pond Armor. It is a little pricey for me. I beleive I would look at using a PVC or EPDM pond liner first.

    I notice you accepted my friend invite on Facebook. Take a look at the CAD drawing and my ground breaking for my aquaponic greenhouse. I am waiting on the covering to arrive now. I thin this will be the final design I go with, using the large IBC Totes (275 Gallons Each)for fish tanks and then building the growbeds from lumber and using a 45 mil pond liner to line the growbeds.

  5. I did tried two part epoxy before on concrete, its about USD 40.00 per can over here about 4 litre.

    On rubberise epoxy my last application to concrete tank it peeled off once water soak occur. It may be due to my bad application of it.

    So I decide to go the old fashion way, just let it be.. :) It does cause my PH to be around 7.5

  8. Best renovating art of the concrete material by establishing the curing procedure with first reference should be given by the curing compound manufacturer in India in different way. Thanks for giving this important information.
