What Makes UNS Contrasand Special?

When choosing substrate for your aquarium, two main factors come into play: granular size and colouration. These aspects impact not only the visual appeal but also the maintenance and health of your tank inhabitants.

Granular size affects how easy it is to clean and maintain the substrate. Finer sands can sometimes be more challenging to clean because they are easily disturbed and stirred up, creating cloudy water. On the other hand, coarser substrates tend to stay put better and make maintenance easier.

Colouration influences the overall mood and natural feel of your aquarium. Natural-looking sands help mimic riverbeds and lake bottoms, creating a more authentic environment for your fish and plants.

The UNS Contrasand family offers a range of options that balance these two factors beautifully, providing substrates that not only look fantastic but also support healthy aquarium environments.

Mojave Sand: Dark and Refined

One of my personal favourites from the Contrasand family is Mojave sand. This substrate is a little finer in grain size, which gives it a smooth, refined texture that's perfect for detailed aquascapes.

What I love most about Mojave is its dark coloration. Unlike natural-coloured sands, Mojave offers a deep, rich tone that creates a striking contrast with typical aquarium stones like dragon stone or seiryu stone. This contrast really makes your hardscape elements pop and adds depth to your aquascape.

Though Mojave sand is on the finer side, it remains manageable in terms of maintenance. It’s a fantastic choice for those who want a sleek, modern look with a substrate that enhances the colours of their aquatic plants and fish.

Bora Sand: The Classic Natural Look

Next up is Bora sand, arguably the most popular sand in the freshwater aquarium hobby—and for good reason. Bora mimics the natural sandy riverbeds you’d find in the wild, with a neutral, light coloration that blends seamlessly with nearly any aquascape.

Its slightly larger granular size compared to Mojave makes it easier to maintain. The grains settle well and don’t get stirred up as easily, which helps keep your aquarium water clear. This is especially beneficial for beginners or those who prefer low-maintenance tanks.

One of Bora’s standout features is its versatility. Whether you’re using dragon stone, seiryu stone, or any other hardscape material, Bora sand complements them beautifully. It provides a natural foundation that enhances the overall harmony of your tank, making it a reliable, all-around substrate choice.

Kona Gravel: The Riverbed Vibe

While Mojave and Bora are sands, Kona is technically a gravel substrate but still part of the UNS Contrasand family. Kona offers a unique look that’s perfect if you want to recreate a river environment in your aquarium.

Kona’s grains are larger and more varied in size, giving it a natural gravel appearance that mimics riverbeds and streams. This gravel-like texture provides excellent water flow through the substrate and is less prone to clouding your tank water when disturbed.

Personally, I’ve been using Kona in many tanks, including some pico tanks on my desktop. It looks fantastic on its own but also blends well when mixed with other gravel-type substrates. This mix can create a dynamic, natural-looking riverbed that elevates your aquascape’s realism.

Kona’s darker coloration evokes the feeling of dark water rivers, adding a moody, immersive vibe to your aquarium. It’s a substrate that works especially well in tanks focused on native or wild river biotope setups.

How to Choose the Right UNS Contrasand for Your Aquarium

Choosing the right substrate depends largely on the look you want to achieve and the practical considerations of maintaining your tank. Here are some tips to help you decide:

• For a sleek, modern look: Go for Mojave sand. Its fine grain and dark colour create a stunning contrast with stones and plants.
• For a natural, classic riverbed feel: Bora sand is your best bet. It’s easy to maintain and blends well with most aquascapes.
• For a gravel riverbed vibe: Kona gravel offers texture and a natural look that mimics wild river substrates.

Maintenance is also a key consideration. If you’re new to aquarium keeping, Bora’s larger grain size makes it easier to clean and maintain clear water. For experienced aquascapers who want precise aesthetics, Mojave’s finer grains offer more control and detail.

Mixing substrates can also be a creative way to achieve unique looks. For example, combining Kona gravel with other gravel substrates can replicate complex riverbeds with multiple textures and colours.

Benefits of Using UNS Contrasand

Beyond their visual appeal, UNS Contrasand substrates offer several advantages that make them a great investment for your aquarium:

1. Natural Appearance: These substrates mimic real-world riverbeds and lake bottoms, creating a realistic environment that supports the well-being of fish and plants.
2. Easy Maintenance: Especially with Bora and Kona, the granular sizes help reduce stirring and cloudiness, making tank upkeep simpler.
3. Compatibility: UNS Contrasand works well with popular hardscape materials like dragon stone and seiryu stone, allowing you to create cohesive and eye-catching aquascapes.
4. Healthy Environment: The substrates provide a stable base for plant roots and beneficial bacteria, promoting a balanced ecosystem in your aquarium.
