Aquaponics 8: Growbed finished (almost)

Hello all,

So, with the pump functioning (wouldn't say working well - it has troubles getting enough water pumped vertically into the air, which is something I'll have to fix later...) it was time to add the Leca nuts my son washed into the grow bed:
I'm so proud. It looks like it is working! Here you can see the water entering in the top right corner. Gravity pulls it though my 'clever' maze system, slowly getting through the holes drilled in the acrylic. It then exits through the draining system in the top left corner - the string is just there to make sure it exits correctly and doesnt drip when the water level is low.
Looks like it should work, doesnt it?

And here the 'emergency drain' (middle left) is visible. After these pictures I had an epiphany and considered how easy the Leca would clutter the 'round hose pipe draining system components' (I might copyright that nonsense later...) and I had to silicone a quick grate solution onto all of these.
 My assistant. Very proud. And very adorable, if I do say so myself :-) He has 'helped' throughalmost all the stages so far.
 We'll have another picture of the chap :-).

Cost so far: 8$ for the silicone used.

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,
