Choosing The Right Substrate

UNS 45t substrates

Bora Sand

The Bora variety of Controsand is an extra fine sand containing a mixture of lighter tones that is perfect for highlighting vibrant aquatic plants, tropical livestock, and darker layout materials. Bora is ideal for a wide variety of popular aquascaping styles.

Kona Gravel

The Kona variety of Controsand is a rounded pebble gravel designed for freshwater aquarium use. Kona’s deeper tones can be used as a supporting feature or to create excellent contrast. Like other Controsands, Kona can be used alone or mixed with other substrates for a custom look in planted tanks, terrariums, paludariums and more.

Mojave Sand

The Mojave variety of Controsand is an extra fine sand containing a mixture of warmer tones. Mojave is ideal for creating natural scenes and compliments Dragon Stone and driftwood nicely. Both Controsand Extra Fine and Normal may be used on their own. However, mixing both can completely transform the look of an aquarium.

Controsoil (Brown or Black)

Choosing a quality substrate is an essential part of a planted aquarium as it provides vital nutrients for lush plant growth and helps balance water parameters. Over time, it stabilizes pH levels to around 6.8, making it ideal for most tropical fish and shrimp that prefer slightly acidic water. 

Originating in Japan, Ultum Nature Systems Controsoil consists of high-quality natural soil and volcanic ash. Controsoil provides the perfect level of nutrients without excess. It can be used alone or capped with other substrates such as UNS Controsand.

Hardscapes For Your UNS 45T Aquarium

UNS 45t Rock and wood

Spider Wood

Spiderwood, also known as Azalea wood or Manzanita wood, is sought after in aquariums for its aesthetic appeal and functional advantages. Its intricate branching structure and unique shapes add natural beauty to tank landscapes while offering hiding places and shelter for small fish, shrimp, and other aquatic inhabitants. Like cholla wood, spiderwood's porous surface encourages the growth of beneficial biofilm, enriching the aquarium ecosystem. While not as potent as cholla wood, spiderwood can release tannins, contributing to a slight reduction in pH and softening of water, which can benefit certain species. Additionally, spiderwood is durable and resistant to decay, making it a long-lasting addition to aquarium setups. Overall, spiderwood is prized for its ornamental qualities and its ability to enhance the habitat and well-being of aquarium dwellers.

Black River Rock

River rock is a favored choice for aquarium enthusiasts due to its aesthetic appeal and practical benefits. Its smooth and rounded appearance mimics the natural riverbed, creating a visually pleasing environment within the tank. River rocks provide excellent hiding places and shelter for small fish, shrimp, and other aquatic creatures, promoting a sense of security in the aquarium habitat. Moreover, river rock is inert and does not significantly affect water parameters, making it suitable for a wide range of aquarium setups. Its inert nature also ensures that it won't alter the pH or hardness of the water, providing stability to the aquatic environment. Additionally, river rock is durable and easy to clean, making it a low-maintenance option for aquarists.

Seiryu & Dragon Stone

Seiryu stone and dragon stone are popular choices for aquascaping due to their visually striking textures and patterns, such as the intricate layers and veins of white and blue-gray in Seiryu stone, and the rugged appearance resembling dragon scales in dragon stone. Beyond aesthetics, these stones offer functional benefits by providing ample surface area for beneficial bacteria colonization, aiding in biological filtration, and creating caves and hiding spots for fish and invertebrates, thus mimicking natural habitats and reducing stress. Additionally, their neutral properties make them safe for most freshwater aquarium setups, contributing to the overall health and well-being of aquatic ecosystems while enhancing their visual appeal.


Driftwood can serve as a functional component by providing shelter, hiding spots, and breeding areas for fish and invertebrates, helping to reduce stress and promote natural behaviors. Driftwood also releases beneficial tannins into the water, which can help lower pH levels and create a more natural environment for certain species, such as those originating from blackwater habitats.
