Aquaponics 4: Fancy plans gets siliconed...

Hello all,
So now the time has come to turn my free growbed (AKA plastic milktray-thingie) into a true grow bed:

As the thing is smaller than I would have preferred and I want to increase the little amount of water I can send through the constant flood-system I decided to get sneaky... Also because I like to complicate things. A lot.

So I silicone "glued" three pieces of Acryl plastic into it to form a small maze. This should (...) force the water through as much os the Leca Grow medium as possible. Oh, and using Aquarium safe silicone, always.

Proof of concept. Well sort of. The water ran much to fast through so I decided to close tha gaps and drill smalle holes for the water. Really wish I had done this more carefully. I think this will come back to haunt me...

 Also I found out (with only a few liters of water on the floor) that I would need to plug up those holes for the hands at each end. Again I really wish I had done a better job at this. And here you can see what type of stuff you find within hands reach when needing something to weigh down pesky things :-).

Oh well, its only a test and its not like the water will ruin anything, right? Right?

Cost so far: 8$ for the silicone as my old stash had dried out (why does it always do that. Argh!).

For those not yet privy to the fascinating world of Aquaponics here is what information Wikipedia provides:

Aquaponicsis a sustainable food production system that combines a traditional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In aquaculture, effluents accumulate in the water, increasing toxicity for the fish. This water is led to a hydroponic system where the by-products from the aquaculture are filtered out by the plants as vital nutrients, after which the cleansed water is recirculated back to the animals. The term aquaponics is a portmanteau of the terms aquaculture and hydroponic.
Aquaponic systems vary in size from small indoor or outdoor units to large commercial units, using the same technology. The systems usually contain fresh water, but salt water systems are plausible depending on the type of aquatic animal and which plants. Aquaponic science may still be considered to be at an early stage, relative to other sciences.

Basicly, this translates into let the fish shit, let the plants grow on the shit and clean the water, and then eat all the plants yourself... more or less....

All the best,
