Duralastics Reservoir | Professional Flat Hydroponic Nutrient Tank Australia

The Duralastics Reservoir is a professional-grade low-profile nutrient tank manufactured in the USA from 100% recycled black ABS plastic at 0.160 inch gauge thickness. Available in 75 gallon (284L) and 100 gallon (378L) configurations, Duralastics reservoirs are the preferred choice for commercial flood and drain operations, large recirculating drip systems, and controlled environment agriculture where standard round or square reservoirs do not suit the available floor plan. The flat rectangular profile maximises floor space utilisation and sits under grow benches and flood trays without raising the reservoir height.

Why Flat Profile Reservoirs Are Used in Commercial Growing

Round and square reservoirs waste floor space in rectangular grow rooms. A flat-profile reservoir like the Duralastics sits under a flood tray or grow bench, keeping the floor plan efficient and maintaining a low reservoir height for gravity-fed systems. The 75 gallon version at 125x125x37cm and the 100 gallon version at the same footprint at a slightly greater depth provide large-volume nutrient storage in a footprint that does not compete with canopy space above.

The built-in water level indicators on the exterior of each reservoir allow quick visual confirmation of solution volume without removing lids, lifting covers, or measuring manually. For commercial growers running multiple reservoirs, this significantly reduces daily monitoring time.

Construction and Durability

Duralastics reservoirs are manufactured from 100% recycled ABS plastic, which is resistant to the dilute acids and oxidising agents present in hydroponic nutrient solutions. The 0.160 inch gauge thickness provides structural rigidity under full load without the flex common in cheaper reservoir designs. The easy-clean interior design eliminates sharp internal corners where biofilm and salt deposits accumulate, making end-of-cycle cleaning significantly faster than conventional reservoirs.

Frequently Asked Questions

What is the difference between the 75G and 100G Duralastics reservoir? The 75 gallon (284L) model suits large recirculating systems and commercial flood tables up to approximately 120x120cm. The 100 gallon (378L) provides additional volume for larger flood tables, multi-bay recirculating systems, or applications requiring more buffer capacity between refills.

Is the Duralastics reservoir suitable for DWC? The flat profile makes it less suited to traditional DWC where you need depth for root submersion, but it works well as a central reservoir for recirculating DWC and RDWC systems where the reservoir feeds multiple grow sites.

What are the shipping costs for the Duralastics reservoir? Due to the large physical dimensions, both Duralastics models ship at Heavy Freight rates. Zone 1 (VIC/NSW/QLD/SA/ACT) shipping is $149.95. WA, NT, and Tasmania require a manual freight quote. This is shown transparently at checkout.

Does the Duralastics reservoir come with a lid? No lid is included. Contact us for compatible lid options for your specific configuration.
