Fluid Farms hybrid striped bass

The rafts beds are 1 foot deep. The system is one big closed loop. We have 4 fish tanks that flow into our filtration which then flows into the raft beds and is then pumped back to the fish tanks.
I would love to show everyone the system but we are finalizing our GAP certification (Good Agriculture Practices) and having outside folks in the greenhouse can get kind of tricky from a food safety stand point. There are lots of rules that we need to follow now. But I would be happy to answer questions if people have any!
