This aquaponic unit is a research , demonstration and educational unit growing rainbow trout ( in the first instance) in tanks.
In simple terms:
The fish are fed proprietary feed dependant on their weight.
The fish water is then pumped through clayball growbeds which act as a filter and provides the necessary feed for the growing plants.
The cleansed water is then returned to the fish tanks.
This is a circulatory water system with the only top up of water required being through the loss of water due to evaporation.
The plants grown here will be primarily herbs and salad crops and later trialing other vegetables and crops.

Trying out the layout for fish tanks and growbeds:
Working on the drain outlet for the growbeds:
Wood has been glued to underside of growbeds to hold the pipework.
The orange bits are part of the B+Q workstands which are supporting the growbeds
