The Ultum Nature Systems Dual All-In-One Aquarium is designed to make fishkeeping and aquascaping simple, elegant, and enjoyable. With its integrated triple-chamber filtration system and premium rimless glass construction, the Dual AIO line is perfect for both freshwater aquascapes and saltwater nano reefs.
If you’re just starting out, this guide will walk you through step-by-step instructions to set up your Dual AIO aquarium successfully.
Step 1: Unboxing and Preparing the Tank
Each UNS Dual AIO aquarium comes with:
- A rimless low-iron glass tank with 91% clarity
- Rear triple-chamber filtration system
- Adjustable submersible pump
- Coarse sponge filter
- UNS Bio Bricks for biological filtration
Before you begin, place the tank on a level surface with the included mat. This helps distribute weight evenly and protects the glass.
Step 2: Understanding the Filtration System
The Dual AIO series features a three-stage rear filter chamber:
1. Chamber One – Coarse sponge to catch debris and waste.
2. Chamber Two – UNS Bio Bricks to cultivate beneficial bacteria.
3.Chamber Three – Pump chamber, circulating water back into the main display.
This integrated system eliminates the need for bulky external filters, keeping your setup clean and minimalist.
Step 3: Adding Substrate and Hardscape
Choose your substrate depending on your planned setup:
- Freshwater planted tank: Use nutrient-rich aquarium soil to support plant growth.
- Saltwater nano reef: Add aragonite sand or fine crushed coral for buffering.
Place hardscape materials such as rocks and driftwood into the tank before adding water. Build stable structures now to avoid collapse later.
Step 4: Filling the Aquarium
Slowly add dechlorinated water into the tank, pouring onto a plastic bag or plate to prevent disturbing the substrate. Fill until the waterline just covers the intake slots for the filter.
Turn on the submersible pump to start circulation. Adjust the flow to match your chosen livestock — lower for shrimp and bettas, stronger for reef corals and marine fish.
Step 5: Planting and Aquascaping
Add aquatic plants or corals once the tank is filled. For freshwater setups, consider easy species such as Anubias, Java fern, or Cryptocoryne. For saltwater, add live rock and consider hardy corals once water parameters are stable.
Attach plants to driftwood and rocks using aquarium glue or thread, and place root feeders into the substrate.
Step 6: Cycling the Aquarium
Before adding fish or shrimp, you’ll need to cycle the tank. This process establishes beneficial bacteria in the filter media that break down waste.
- Add an ammonia source (fish food or bottled bacteria starter).
- Monitor ammonia, nitrite, and nitrate levels.
- Once ammonia and nitrite are zero, your tank is cycled and ready for livestock.
This step usually takes 3–4 weeks, but ensures a healthy environment for your animals.
Step 7: Optional Upgrades and Accessories
UNS offers a range of accessories to customise your Dual AIO aquarium:
- Media Tower – For layered filtration and easy maintenance.
- Refugium Module – Ideal for reef keepers growing macroalgae.
- Protein Skimmer – For advanced saltwater systems.
- Auto Top-Off (ATO) unit – Maintains stable water levels.
- Intake Guard – Protects shrimp and fry from filter intake.
These additions enhance stability and reduce maintenance for long-term success.
