When it comes to maintaining crystal-clear water in a reef tank, a reliable protein skimmer is a must. Few brands are as trusted as Nyos, whose Quantum series has become a favourite among both hobbyists and professional reef keepers. But with several models in the range — including the Quantum 120, 160, and 220 — it can be tricky to decide which one suits your setup best.
In this guide, we’ll break down the Nyos Quantum Skimmer range, explain how they work, and help you choose the right model for your aquarium.
Why Protein Skimming Matters
Protein skimmers play a vital role in removing organic waste before it breaks down into ammonia, nitrite, or nitrate. By extracting dissolved organics, skimmers improve water clarity, stabilise pH, and create a healthier environment for corals and fish.
A good skimmer reduces the workload on biological filtration and minimises algae growth — giving your reef tank that clean, polished look every reefer wants.
Why Choose a Nyos Quantum Skimmer?
Nyos Quantum skimmers are engineered in Germany and known for quiet operation, energy efficiency, and exceptional performance. They combine advanced design with user-friendly features, making them one of the most reliable choices for marine aquariums.
Some standout features include:
- Hybrid Wheel impeller: produces ultra-fine microbubbles for efficient waste removal.
- Clear view reaction chamber: allows you to see exactly what’s going on inside.
- Silencer system: keeps operation whisper-quiet, ideal for tanks in living spaces.
- Tool-free maintenance: easy to disassemble and clean.
Whether you’re running a nano reef or a 500-litre system, Nyos has a Quantum skimmer for you.
Nyos Quantum 120 – Perfect for Small to Medium Tanks
If your aquarium is under 500 litres, the Nyos Quantum 120 is an ideal fit. It’s compact yet powerful, pulling out impressive amounts of waste for its size.
This model is perfect for reefers who want professional performance without a bulky footprint. Its energy-efficient pump draws minimal power, making it both eco-friendly and cost-effective.

Nyos Quantum 160 – Balanced Power for Growing Reefs
Moving up a level, the Nyos Quantum 160 is designed for medium to large systems up to around 1000 litres. It’s a favourite among reefers who are expanding their coral collections or upgrading their systems.
The larger reaction chamber and stronger pump provide superior foam production, improving nutrient export and maintaining pristine water even in heavily stocked tanks.
Best for:
- Medium to large reef tanks
- Reefers looking for stronger nutrient export
- Tanks with heavier bioloads
Nyos Quantum 220 – For Serious Reef Systems
At the top of the range sits the Nyos Quantum 220, a powerhouse built for large aquariums up to 2000 litres. This model is the go-to for experienced hobbyists and public display systems that demand consistent, high-volume skimming.
Its oversized reaction chamber, high-capacity pump, and premium build quality ensure top performance with minimal maintenance. It’s built to run continuously and handle even the most demanding setups.
Best for:
- Large and heavily stocked reef systems
- Advanced hobbyists or commercial displays
- Those prioritising performance and reliability
How to Choose the Right Model
When choosing your Nyos Quantum skimmer, consider:
- Tank volume – Match the skimmer to your total water volume (including sump).
- Bioload – More fish and coral mean more waste; go one model higher if your tank is heavily stocked.
- Space – Measure your sump or cabinet area to ensure a comfortable fit.
- Noise tolerance – All Quantum skimmers are quiet, but larger models have slightly deeper hums.
