The new aquaponics set up in better detail

I took a few pictures for any who might be curious to the design of my system.  It is a simple system where the fish tank is below the plant grow bed.  The water is pumped up to the plant grow bed and then gravity drained back.  The gravity drain starts when the water in the plant grow bed reaches a certain level thus creating a siphon which then drains until the siphon suction is broken.

The vertical towers are on a separate pump.  The water is pumped from the fish tank to the towers in a series.  The water drains down the towers and is collected in a bucket which once a certain water level is reached, the water returns to the fish tank via gravity drainage again.  My new best friends are bulkheads and a hole saw.
