{"product_id":"hydroponic-reservoir-160l-220l-tank","title":"Hydroponic Reservoirs | 160L \u0026 220L Nutrient Tank Systems","description":"\u003cp\u003eWhen you're running a serious hydroponic system, a 45L tub under your bench stops being enough. Multi-plant drip systems, commercial flood and drain setups, and large recirculating grows need a reservoir that can hold enough solution to run the system through multiple feed cycles without constant top-ups. These 160L and 220L hydroponic reservoirs are built for exactly that scale.\u003c\/p\u003e\u003cp\u003eConstructed from heavy-duty UV-stabilised plastic with a light-blocking opaque finish, they maintain stable nutrient conditions by preventing the light penetration that triggers algae growth in open or translucent tanks. At 160 and 220 litres, they provide enough capacity to supply multi-site drip systems, large flood and drain trays, and DWC setups with consistent nutrient solution without the daily maintenance burden of smaller containers. Compatible with standard tub outlet fittings, grommets, and submersible pumps, they integrate directly into existing hydroponic plumbing without modification.\u003c\/p\u003e\u003ch2\u003eHow It Works\u003c\/h2\u003e\u003cp\u003eFill the reservoir with water and mix your nutrient solution to the target EC and pH. Place your submersible pump inside the reservoir to feed your irrigation system, or drill and fit tub outlet fittings through the wall for gravity-fed or recirculating connections. The opaque walls block all light from reaching the solution, preventing algae from establishing. The reinforced structure handles the full weight of a 160L or 220L solution load without flexing, keeping the reservoir stable and upright throughout the grow cycle. Top up as needed and monitor EC and pH regularly to maintain consistent nutrient delivery.\u003c\/p\u003e\u003ch2\u003eKey Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable in 160L and 220L capacities.\u003c\/strong\u003e Sized for multi-plant systems, commercial grow operations, and large flood and drain setups that require consistent nutrient supply across extended periods.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight-blocking opaque construction prevents algae growth.\u003c\/strong\u003e Solid walls eliminate light penetration into the nutrient solution, removing the primary trigger for algae blooms that cloud reservoirs and compete with plants for oxygen.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-duty UV-stabilised plastic.\u003c\/strong\u003e Built for continuous use in nutrient-rich environments, resisting the chemical exposure and temperature variation of indoor grow rooms and greenhouse operations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with standard hydroponic fittings.\u003c\/strong\u003e Can be drilled to accept tub outlet fittings in 13mm, 19mm, and 25mm, and grommets for airline pass-throughs, making them fully integrable into custom system builds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports pump-driven and gravity-fed systems.\u003c\/strong\u003e Works as a central supply reservoir for drip irrigation, flood and drain, DWC, and recirculating nutrient systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStable nutrient solution storage.\u003c\/strong\u003e Large volume reduces concentration fluctuations caused by plant uptake and evaporation, maintaining more consistent EC and pH between top-ups.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentral nutrient reservoir for multi-plant drip systems\u003c\/li\u003e\n\u003cli\u003eFlood and drain system reservoir supply\u003c\/li\u003e\n\u003cli\u003eDeep Water Culture (DWC) nutrient tank\u003c\/li\u003e\n\u003cli\u003eCommercial hydroponic grow room nutrient storage\u003c\/li\u003e\n\u003cli\u003eGreenhouse irrigation supply tanks\u003c\/li\u003e\n\u003cli\u003eNutrient solution mixing and storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacities.\u003c\/strong\u003e 160L \/ 220L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial.\u003c\/strong\u003e Heavy-duty UV-stabilised plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour.\u003c\/strong\u003e Black (light-blocking)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction.\u003c\/strong\u003e Nutrient storage and irrigation supply\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility.\u003c\/strong\u003e Tub outlet fittings, grommets, submersible pumps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication.\u003c\/strong\u003e Hydroponics, drip irrigation, flood and drain, DWC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironment.\u003c\/strong\u003e Indoor, greenhouse, commercial systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate Weight (empty).\u003c\/strong\u003e 160L approx. 5 to 7 kg, 220L approx. 7 to 10 kg\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently Bought Together\u003c\/h2\u003e\u003cp\u003eTurn this reservoir into a complete irrigation hub.
