Marine Fish & Invertebrate Systems
Designed specifically for saltwater environments, our marine fish and invertebrate systems provide exceptionally stable and efficient conditions for even the most delicate marine species. Every unit is built using high-grade, corrosion-resistant materials and engineered to support precise salinity, temperature, and flow requirements essential for healthy marine livestock.
Available as modular units or fully bespoke builds, these systems are ideal for housing clownfish, gobies, shrimp, soft corals and a wide range of marine invertebrates. Our advanced marine filtration packages are tailored to maintain excellent water clarity, nutrient control and biological stability, while easy-access maintenance points allow staff to manage day-to-day husbandry quickly and confidently.

Tropical Freshwater
Here is a refined, SEO-optimised version that aligns perfectly with the tone of your other sections and boosts discoverability for Google and AI models:
Our tropical freshwater systems are engineered for reliability, ease of use and vibrant livestock display. Suitable for a wide range of community fish species, these systems provide stable temperatures, highly efficient mechanical and biological filtration, and simple day-to-day maintenance for busy retail environments.
Each unit can be configured to suit your shop’s layout, with flexible options for 2-, 3- or 4-tier racking. Whether you are housing tetras, barbs, cichlids or catfish, our systems maintain excellent water quality, strong oxygenation and clear visibility. Built from durable, long-lasting materials and powered by low-wattage equipment, they deliver healthy fish, minimal losses and consistently low running costs.

Pond Systems
Engineered for strength, durability and long-term performance, our outdoor pond systems are ideal for housing koi, goldfish and a wide range of ornamental pond species. Constructed from high-grade fibreglass and paired with robust, low-maintenance filtration options, these systems are built to withstand year-round outdoor conditions for decades.
From compact quarantine and treatment units to large-scale holding tanks, we offer flexible designs tailored to garden centres, fisheries and aquatic retailers. Every system prioritises water quality, visibility and ease of maintenance, ensuring healthy stock, reduced labour and reliable day-to-day operation.
State-Of-The-Art



Aquarium Rack Systems for Pet Retail
State-of-the-art fish racking systems for aquatic shops
Custom solutions for every layout and livestock requirement
Drawing on decades of professional aquaculture experience, we design and manufacture state-of-the-art aquarium racking systems for the aquatic retail sector. Our systems are available in 2-, 3- or 4-tier configurations and can be built around a wide range of tank sizes, depths and water volumes, giving you complete flexibility for your livestock mix.
Livery can be customised to match your company colours, or we can work with your design team to create a fully bespoke look. We also provide expert guidance on selecting the ideal filtration method for your shop’s stocking levels and water type.
Price beating policy
We are committed to delivering exceptional value. Our Price Beating Policy means we aim to surpass any like-for-like quote from competitors—not only on price, but also on lead times, service quality and overall system efficiency.
Low-maintenance design
Our aquarium display units are engineered for fast, simple, and reliable daily operation. Filtration systems are easy to access and quick to clean. A straightforward valve layout allows staff to be trained rapidly, and where possible, waste water can be routed directly to a drain and automatically topped up, reducing labour and improving hygiene.
Low running costs
Every system is designed with energy efficiency in mind, using low-wattage lighting and pumps to keep operating costs down. We are also launching our new eco-range of racking systems, focused entirely on minimising electricity consumption while maintaining excellent water clarity and fish health.

As one of the world's leading developers of aquatic systems, we specialise in high-efficiency aquarium racks, fibreglass pond systems and commercial filtration solutions for the pet retail, aquaculture and public-aquarium sectors. Our designs focus on optimum water quality, energy efficiency and long-term reliability, supported by decades of practical experience in fish husbandry and aquatic engineering. Whether you require tropical, marine, coldwater or koi-holding systems, we provide fully engineered solutions tailored to professional settings, ensuring healthy livestock, clear display tanks and reduced daily maintenance.
My mission as director is to apply advanced aquaculture principles to every aquarium rack, fibreglass pond and filtration system we produce. I believe that even small retail systems deserve the same engineering attention as large public-aquarium installations. By focusing on surface-area-to-volume ratios, flow dynamics and energy-efficient design, we aim to create systems that deliver stable water quality, strong fish health and dependable performance all year round. Our ambition is to remain the most trusted provider of aquatic systems in the UK.
Ben Woodward
Chairman and Director
With a proven track record in aquaculture and aquatic engineering, we design and manufacture high-performance aquatic systems tailored to professional use. Our expertise spans aquarium racking for the pet retail sector, fibreglass holding tanks for fisheries, advanced marine systems for public aquariums and precision zebrafish systems for research laboratories and universities. Each build is carefully calculated using surface-area-to-volume ratios, optimised flow patterns and efficient biological filtration to ensure healthy livestock, clear displays and reduced labour for staff. By focusing on robust construction, low-wattage components and high water quality stability, we deliver systems that outperform traditional retail units while providing long-term reliability and excellent value for money.
