DESIGNED FOR AQUACULTURE
Purpose-Built for Efficient Fish Handling
Every tank has a sloping bottom with a purpose-built all-poly base, and a sump moulded in one piece with the tank. Tank height is designed for efficient fish handling, and there is no internal pipework inside the tank to damage fish or get in the way.
A poly water level controller fits under the top lip of the tank, and a pump is available as an additional extra.

Plenty of operations run aquaculture and crop. If yours does, these are the tanks that handle the fertiliser side, built from the same durable polyethylene as the aquaculture range.
Self-Draining Liquid Fertiliser Tanks
A clean supply source for the fertigation line. The sloped base clears out completely, so there is no settled residue getting drawn into your dosing gear and throwing off application rates.

Flat Bottom Liquid Fertiliser Tanks
The bulk reservoir a fertigation setup runs off when you are injecting steadily across a season. Maximum holding volume for the footprint, so you refill less often during peak application.

Fertigation Tanks
Set up to dose liquid fertiliser directly into an irrigation line, so nutrient goes out with the water rather than in a separate pass. The option when you are feeding a crop through the same system that waters it.

FAQs
Frequently Asked Questions
What is an aquaculture tank?
An aquaculture tank is an open vessel built for holding and handling live fish or other aquatic stock, usually with a sloping base and a moulded sump so it drains fully for cleaning. Polymaster’s range runs from 200L to 9,000L, built for efficient fish handling with no internal pipework to get in the way.
Are poly aquaculture tanks as good as fibreglass tanks?
Polyethylene tanks have no joins, seams, or part-lines, since they are moulded in one piece, which matters for fish handling where a rough edge or seam can cause injury. They are also food-grade and UV-stabilised for long-term outdoor use, which is a common failure point for ageing fibreglass tanks.
What size aquaculture tank do I need?
It depends on the number and size of fish you are holding and how often you need to handle or transfer them. The range runs from 200L for small-scale setups up to 9,000L for larger operations, all with the same sloping base and sump design for consistent handling.
Can aquaculture tanks be used for tilapia and other fish species?
Yes, the tanks are suited to a range of species including tilapia, provided stocking density and water quality are managed appropriately for your setup. For specific stocking advice, it is worth checking with an aquaculture specialist, since requirements vary by species.
