Built for Hydroponic Nutrient Storage
AQUA-TANK is particularly well suited to use as a hydroponic nutrient reservoir.
Hydroponic irrigation systems often require a central tank for preparing and storing water or nutrient solution before it is supplied to plants.
AQUA-TANK provides a practical reservoir for applications including:
- Hydroponic nutrient storage
- Nutrient mixing
- Automatic irrigation systems
- Run-to-waste systems
- Recirculating systems
- Coco irrigation
- Reservoir top-up water
- Greenhouses
- Indoor gardens
- Horticultural irrigation
- Commercial growing environments
The multiple capacity options also make it possible to select a reservoir appropriate for the scale of the growing system.
Heavy-Duty 500D PVC Construction
AQUA-TANK is manufactured from BPA-free, non-toxic, UV-resistant 500D heavy-duty PVC.
The material provides the flexibility required for a collapsible tank while remaining robust enough for substantial water-storage applications.
The construction also incorporates reinforced stitching and quality fittings, helping provide durability for repeated use.
Designed for Australian Conditions
AQUA-TANK is 100% Australian owned and designed for Australian conditions.
UV resistance is particularly important for water tanks used in environments where exposure to strong light or outdoor conditions is possible.
Combined with its heavy-duty construction and reinforced stitching, AQUA-TANK provides a purpose-designed alternative to improvised nutrient and water-storage containers.
Collapsible, Portable & Space Saving
One of the biggest advantages of AQUA-TANK is its ability to collapse when empty.
Conventional rigid reservoirs continue occupying their full footprint even when they aren't being used.
AQUA-TANK can instead be emptied, cleaned, dried and packed down for storage.
This makes it particularly useful for:
- Seasonal growing
- Temporary grow rooms
- Changing grow-room layouts
- Rental properties
- Limited storage areas
- Portable irrigation systems
- Greenhouses
- Temporary nutrient reservoirs
- Gardens where permanent tanks aren't practical
Fits Where Rigid Reservoirs Can't
Large rigid reservoirs can be difficult to install in established growing environments.
Doors, narrow hallways, stairways and existing grow-room equipment can all restrict access.
Because AQUA-TANK arrives compact and unassembled, it can be carried into the required location before being expanded and assembled.
This makes it an excellent solution for indoor hydroponic rooms where installing a conventional rigid tank of equivalent capacity may be impractical.
Easy Tool-Free Assembly
AQUA-TANK is designed for simple assembly without tools.
The flexible reservoir is supported by external support legs that maintain its structure once assembled and filled.
For best results, always position the reservoir on a:
- Firm surface
- Flat surface
- Clean surface
- Stable location
- Surface capable of supporting the total filled weight
The reservoir should be fully positioned before filling.
Remember that 1 litre of water weighs approximately 1kg, meaning a 1000L reservoir can contain approximately one tonne of water before accounting for the tank itself.
Integrated Outlet Tap
AQUA-TANK includes a lower outlet tap that connects to a standard garden hose fitting.
This allows stored water to be conveniently transferred or directed where required.
Potential uses include:
- Garden watering
- Gravity-fed watering
- Reservoir draining
- Water transfer
- Irrigation connections
- Rainwater distribution
The exact irrigation configuration will depend on the flow requirements and equipment used in the growing system.
Top Access Opening
The reservoir lid includes a useful top access opening.
This provides access for suitable equipment without requiring the entire lid to remain open.
Depending on the setup, growers can use the opening for items such as:
- Air hoses
- Airstone lines
- Submersible water heater cables
- Irrigation tubing
- Water lines
- Other compatible reservoir equipment
This is particularly useful for hydroponic systems where nutrient solution needs to be aerated, circulated or temperature managed.
Feed Chart Pocket
A useful feature for hydroponic growers is the integrated feed-chart pocket.
This provides a convenient place to keep important cultivation information close to the reservoir, such as:
- Nutrient schedules
- Mixing instructions
- EC targets
- pH targets
- Feeding notes
- Reservoir records
For commercial or multi-reservoir growing environments, this can also help identify which feeding program is being used with each tank.
Filter & Overflow System
The 100L, 225L, 400L, 750L and 1000L AQUA-TANK models include a filter in the lid and an overflow valve.
The lid filter helps prevent larger debris such as leaves from entering the reservoir when the tank is configured for rainwater collection.
The overflow valve provides a controlled outlet for excess water.
A suitable hose can be connected to the overflow to direct excess water toward another location or potentially onward to additional tanks.
Important Size Note
The lid filter and overflow valve are supplied with the 100L, 225L, 400L, 750L and 1000L models.
They are not included with the 50L model.
Rainwater Collection
AQUA-TANK can also be configured as a convenient collapsible rainwater tank.
For applicable models, rainwater from a suitable downpipe can be directed through the filtered opening in the lid.
The filter helps prevent leaves and larger debris from entering the stored water.
Collected rainwater can then be used for suitable:
- Garden watering
- Horticultural applications
- Irrigation
- Plant watering
- Hydroponic water preparation where water quality is appropriate
Rainwater quality should always be assessed before using it for sensitive hydroponic applications.
Hydroponic Nutrient Mixing
AQUA-TANK provides a convenient central reservoir for preparing nutrient solutions.
Depending on your feeding program, the reservoir can be used for mixing:
- Water
- Base nutrients
- Calcium and magnesium supplements
- Bloom additives
- Root-zone supplements
- Compatible biostimulants
- Other suitable hydroponic additives
Always follow the nutrient manufacturer's specified mixing order and application rates.
For hydroponic nutrient reservoirs, growers should regularly monitor important parameters such as:
- EC / PPM
- pH
- Water temperature
- Reservoir volume
- Nutrient strength
Pumps, Aeration & Reservoir Equipment
The covered design and top access opening allow AQUA-TANK to be incorporated into a wide variety of hydroponic systems.
Compatible equipment may include:
- Submersible water pumps
- Circulation pumps
- Air pumps
- Airstones
- Irrigation pumps
- Water heaters
- Water chillers
- Irrigation tubing
- Nutrient dosing equipment
- Float valves and compatible reservoir accessories
Equipment should always be selected according to reservoir capacity, required flow rates and the design of the irrigation system.
