This is a system that we (Atria Aqua Gardens) recently built for a client in California.
The system consists of 4- 50 gallon media beds and 3- 16' DWC troughs. A 275 gallon sump (recently expanded to 550 gallons), a 300 gallon fish tank, and a 4' by 8' seedling table.
The media beds are "standard issue", but we designed and build the grow bed stands ourselves here in Salina, Kansas.
