Saves Space, Uses Less Energy, Less Seawater & Easier To Operate
If you’re considering a new shellfish purification system you’ll probably be comparing an Oyster Pod with a traditional purification tank. Both will purify shellfish to the required standard, but the Oyster Pod was designed to solve some of the frustrations that customers told us about over the years.
The result is a purification system that saves space, uses less energy, needs less seawater and makes changing between purification cycles much quicker. Better still, it costs no more than many traditional purification tanks.
Quick Answer
The Oyster Pod offers five main advantages over a traditional purification tank:
- Takes up less floor space.
- Uses less electricity.
- Requires less seawater.
- Makes changing purification cycles much quicker.
- Costs no more than many traditional systems.
Why does the Oyster Pod save space?
A smaller footprint gives you more room to work.
One of the first things customers notice is how little floor space the Oyster Pod needs. By stacking the purification trays vertically, the system holds the same amount of shellfish while taking up much less room than a traditional tank.
That can make a real difference whether you’re working in a processing unit where every square metre costs money or making the best use of a garage or outbuilding. Less floor space for the purification system means more room for everything else.
How does the Oyster Pod use less energy?
Gravity does most of the hard work.
Traditional purification tanks generally rely on pumps to keep water moving around the system.
The Oyster Pod works a little differently. The pump lifts the water to the top of the stack and then gravity takes over, allowing the water to flow naturally through each tray before returning to the sump.
Using gravity wherever possible means the system is more energy efficient without compromising performance.
Why does the Oyster Pod need less seawater?
Less water means less work.
Whether you collect natural seawater or mix your own using a sea salt mix and dechlorinated water, preparing seawater takes both time and money.
Because the Oyster Pod uses a smaller volume of water than many traditional systems, there is simply less water to prepare, less water to handle and lower ongoing running costs.
How does the Oyster Pod make purification easier?
No more siphoning water between purification cycles.
For many customers this is the feature they appreciate most once they’ve started using the system.
With a traditional purification tank it’s common to drain the tank or siphon the water into another container before beginning the next purification cycle.
The Oyster Pod makes the whole process much simpler. Turn a valve and the water drains neatly into the sump. When you’re ready to start the next cycle, turn the valve back and the trays refill automatically.
It’s one of those small changes that saves time every time you use the system.
Does the Oyster Pod cost more than a traditional purification tank?
No.
Fibreglass tanks have increased significantly in price over recent years, so the cost difference between traditional systems and the Oyster Pod has largely disappeared.
That means you can benefit from the space-saving design and easier day-to-day operation without paying any more.
Is an Oyster Pod the right choice for your business?
Every shellfish business is different, but most customers are looking for exactly the same thing. They want a purification system that is reliable, straightforward to use and economical to run.
The Oyster Pod was designed with those priorities in mind. By saving space, reducing energy use, using less seawater and making purification cycles easier, it helps save time, effort and money throughout the life of the system.

Frequently Asked Questions
Does the Oyster Pod save space?
Yes. The stacked design uses much less floor space than a traditional purification tank while holding the same quantity of shellfish.
Does the Oyster Pod use less electricity?
Yes. The pump only lifts the water to the top of the stack before gravity moves it naturally through the system.
Does the Oyster Pod use less seawater?
Yes. The system requires a smaller volume of seawater, reducing preparation time and ongoing running costs.
Is the Oyster Pod more expensive?
No. Despite offering several practical advantages, it costs no more than many traditional purification tanks.
