Downweller / Upweller Tank

Ideal for hatcheries looking for downwelling and upwelling capabilities in the same system. Also good for small scale farms looking to grow out a small quantity of small seed.


Hoopers Island Oyster Co’s latest upgraded nursery tanks have been specially designed in house for high efficiency and low maintenance. This new design features a deeper slope bottom and 4” drain to allow for quick and easy cleaning. The tank is elevated by stands and includes 12 silos. Our tanks allow for upwelling and downwelling, whichever is needed, and are equipped ready to use, except for an exterior drain pipe.
