I am currently running 2 systems. One is a tote system with tilapia and the other is a raft system with no fish of course however I do replenish the water from my tote tank in order to capture those rich nutrients created by my tilapia.

Both systems are producing veggies and herbs.

Regards,
Bob

Here are some pix of my systems on Facebook ...
