What is the UNS Dual All-In-One (AIO) Aquarium?
The UNS Dual All-In-One Aquarium is a premium, modern aquarium system designed with simplicity, performance, and aesthetics in mind. It integrates a complete filtration system directly into the back panel of the tank, eliminating the need for bulky external filters, sumps, or complicated plumbing. The result is a clean, minimalist display that is easy to set up, highly efficient, and ideal for both freshwater and marine environments. The “Dual” designation refers to the dual-chamber filtration layout, which separates mechanical, biological, and chemical filtration stages to maintain water quality and support a stable ecosystem.

How does the filtration system work?
The filtration system in the UNS Dual AIO is built into the rear of the aquarium and uses a multi-stage process to keep water clean and stable. Water first flows over the intake weir, skimming the surface and removing debris and protein film. It then passes through a mechanical filtration stage where sponges or filter floss capture particles and detritus. Next, the water moves into a biological filtration chamber filled with porous media, where beneficial bacteria break down toxic ammonia and nitrite. An optional chemical filtration stage can be added to remove dissolved organics or excess nutrients. Finally, the clean water enters the return chamber and is pumped back into the tank through an adjustable nozzle, creating circulation and oxygenation.

Can the filtration media be customised?
Yes, the UNS Dual AIO filtration system is designed to be modular and customisable. Users can easily change or upgrade media to suit their tank’s specific needs. Many aquarists choose to use fine filter floss for clearer water, ceramic or sintered bio media to boost bacterial colonisation, or activated carbon and phosphate removers to control water chemistry. It is also possible to convert part of the filtration chamber into a refugium for macroalgae, which helps with natural nutrient export.

Does the system support refugiums or protein skimmers?
Yes. Many aquarists successfully convert a portion of the rear filtration chamber into a refugium to grow macroalgae, which aids in nutrient control. It is also possible to add compact internal protein skimmers for marine tanks, and these integrate seamlessly without affecting the tank’s

Is the UNS Dual AIO easy to set up?
The UNS Dual AIO is designed for straightforward installation. Most aquarists can unbox, position, and prepare the system within an hour. The setup process typically involves placing the tank on a level, stable surface, installing the return pump and heater, adding substrate and hardscape, and filling the tank with water. Once filled, the tank must be cycled before adding any livestock. Because the filtration is built in, there is no need for plumbing, drilling, or connecting external equipment.

What substrate should I use?
The choice of substrate depends on the type of aquarium you plan to build. For freshwater planted tanks, nutrient-rich aquasoil or plant-specific substrate is recommended, often capped with fine sand. Shrimp or soft-water setups work well with fine sand or inert substrates, while marine tanks typically use aragonite sand or crushed coral to help stabilise pH and provide surface area for beneficial bacteria.

What types of aquascapes are compatible?
The UNS Dual AIO is extremely versatile and works well with many aquascaping styles. It is ideal for nature-inspired layouts such as Iwagumi or Ryuboku, heavily planted jungle-style tanks, nano reefs with carefully arranged rockwork and coral placement, or biotope aquariums that replicate natural habitats. The rear filtration system is hidden from view, allowing the aquascape itself to remain the focal point.

What types of fish and invertebrates can I keep?
The UNS Dual AIO supports a wide variety of aquatic life. In freshwater setups, popular options include community fish like tetras, rasboras, and guppies, as well as bottom dwellers such as Corydoras and Otocinclus. Invertebrates like Amano and cherry shrimp or nerite snails also thrive in these systems. In marine setups, nano reef fish such as clownfish, gobies, and firefish are excellent choices, along with invertebrates like cleaner shrimp, hermit crabs, and various snails. The tank can also support a range of coral species, including soft corals, LPS, and even beginner-friendly SPS.

How soon can livestock be added after setup?
It is essential to complete the nitrogen cycle before adding any fish or invertebrates. This process usually takes four to six weeks. During this time, beneficial bacteria establish themselves in the biological media, breaking down ammonia and nitrite into less harmful nitrate. Only once ammonia and nitrite levels are at zero should you begin introducing livestock.

Only once ammonia and nitrite levels are at zero should you begin introducing livestock.
How many fish can I keep?
Stocking levels depend on the tank’s volume, filtration capacity, and the species being kept. A general guideline for freshwater aquariums is one centimetre of fish per litre of water, while marine tanks should be stocked more conservatively, with roughly one inch of fish per seven to ten litres. Adding livestock gradually helps prevent spikes in ammonia and reduces stress on the biological filtration system.
