Tub Reservoir 65L Black. Mid-Size Hydroponic Nutrient Tank Australia

Tub Reservoir 65L Black. Mid-Size Hydroponic Nutrient Tank Australia

The 65L Black Tub Reservoir is a mid-size food-grade black plastic nutrient tank designed for hydroponic systems that need more capacity than a 45L tub but do not require the full volume of a 160L or 220L reservoir. Black construction blocks light to prevent algae growth in the nutrient solution. At 65 litres, it suits multi-plant recirculating systems, larger DWC setups, and nutrient mixing stations for 5L to 10L batch preparation.

Why 65L Is the Right Size for Many Setups

The jump from 45L to 160L is significant. For growers running 4 to 6 plants in a recirculating drip or ebb and flood system, a 160L reservoir holds more solution than the system needs, which makes pH and EC adjustments slow to take effect and increases the cost of nutrient changes between cycles. A 65L reservoir at the same nutrient concentration requires less product per fill, responds faster to pH correction, and is easier to fully drain and clean between grows.

For growers using the Flood and Drain Trays or Flo-Gro Dripper System, 65 litres provides adequate buffer volume without the overhead of a large tank.

Compatible Accessories

The NEF lid range fits the 65L tub for covered reservoir applications. For smaller capacity needs, see the NEF Solid 23L and NEF Solid 45L tubs. For larger systems, the 160L and 220L reservoirs cover commercial-scale nutrient volumes.

Frequently Asked Questions

Is the 65L tub suitable as a DWC reservoir? Yes. 65 litres supports 2 to 4 plants in a DWC configuration with adequate dissolved oxygen buffer. Cut the lid for net pot holes and air stone access, run an air pump, and the 65L tub functions as a reliable mid-size DWC reservoir.

Does a lid come with the 65L tub? No. The lid is sold separately - see Lids to suit 23/45/65L White.

What is the shipping weight on the 65L tub? The 65L tub ships at volumetric weight and falls in the Bulky Freight tier at $79.95 for Zone 1 (VIC/NSW/QLD/SA/ACT) due to its physical size. Remote area rates apply for WA, NT, and Tasmania.
