A 3,000 m³ grass carp RAS farm in Neijiang, China, delivered by RASTANK.

The full write-up for this project is in preparation. Ask us for the layout, the equipment list and photos, and we send what the farm owner allows us to share.

What a farm like this involves

Every grass carp system starts from the same numbers: species, target output, site and climate. Feed load sizes the biofilter and oxygen, peak flow sizes the drum filter and pumps, and the site sets the tanks.
