I was wondering if there was any interest in Aquaponic systems?
What is an aquaponic system it is aquaculturing ( breeding fish tilapia or others ) and hydroponics ( growing plants with no soil usually a mixture of water and nutrients ) combining the two you get aquaponics.
A normal fish tank has a filter in a aquaponic system the filter is plant line which contains a bio-filter ( usually crushed porous rock and an aerator ) then the water flows through the plants and in to a sump tank where Ph is balanced and any excess particles settle.
There are two different kinds of aquaponic systems continues flow and a "pump and dump" or flood.
There is allot more that can be expanded on aquaponics and i hope there is interest.
interest that go with aquaponics
automation - harvesting, natural Ph balancing, bio fuel etc.
