Hay Mark, Happy to help people out.  There is a Florida Aquaponics Group on the site which might interest you as well.  I know this place can take a little getting used to for finding your way around.

As to the fish tank with NFT.  You need to get some more filtration on there since the NFT doesn't provide much at all.  If you can get your hands on a barrel to cut in half and fill with some non-limestone/marble gravel.  Brown river rock works well as would lava rock.  and hook those up with your system it will take care of converting the toxic ammonia to nitrite then to nitrate which is what the plants will use.  And then you can also plant some large plants in the barrel halves.  If you cut them to make them like big plant pots, you don't even need much support for them.
