Lobster Tanks

Dura-Tech fiberglass lobster holding tanks are built to help keep lobster alive, fresh, and properly held before shipment, sale, or processing. These tanks are designed for commercial seafood environments where corrosion resistance, cleanability, durability, and water quality management are essential.

Fiberglass is well suited to lobster holding because it is rust-proof, lightweight, and resistant to saltwater corrosion. Dura-Tech lobster tanks can be configured for holding capacity, water movement, access, cleaning, and integration with recirculating water treatment equipment.

Dura-Tech can also provide water treatment system components for lobster holding applications, including pump, sand filter, UV filter, and chiller integration. These systems help support water clarity, biological control, temperature management, and ongoing water quality in commercial holding environments.

Water Treatment System

Pump

The recirc pump draws water from the bottom of the lower tank. The pump is designed for efficiency and can be set to maintain a constant user-input flow rate by varying its speed automatically. This allows the user to save energy by pumping only the amount of water needed to maintain desired water quality. It also automatically compensates for a dirty filter by increasing pump speed to maintain a constant flow.

The recirc pump also has a strainer basket on the suction side of the pump to prevent larger items from entering the pump.

There is a valve on both the suction and discharge side of the pump so that the pump can be serviced without water being lost from the system. A check valve on the discharge side of the pump also prevents water from back feeding out the lower tank drain when the pump is off.

Sand Filter

Water flows from the pump to the sand filter which both cleans the water of particles and acts as an ammonia removal biofilter.

UltraViolet (UV) Filter

From the sand filter, the cleaned water proceeds to the upper tank with a portion of the flow being sent through the UV filter for bacterial control. The UV sterilizes bacteria and/or algae faster than they can proliferate. The UV functions not by killing organisms, but by damaging the DNA of cells so that they can no longer reproduce.

Chiller

If a chiller is included with the system, water will flow from the sand filter to the chiller before proceeding to the upper tank. Water should be dropped into the upper tank in the end opposite the overflow stand pipe. Water will exit the upper tank through the stand pipe and pour into the middle tank. From the middle tank, water overflows the standpipe and falls into the lower tank.
