UNS Controsand - Vesuvius
Product Overview
Ultum Nature Systems Controsand offers a versatile lineup of natural decorative sands and gravels designed to give any planted tank or freshwater aquarium a finished, professional look. Vesuvius is a chunky black lava rock aquarium gravel that brings serious dark-mode energy that contrasts beautifully with lighter hardscape and colorful aquatic plants. Its highly porous composition is great for housing beneficial microbes and provides a natural, secure foraging ground for dwarf shrimp and bottom dwellers. Measuring 4mm to 8mm, this dark substrate looks fantastic as a standalone substrate, scattered around hardscape bases, or layered with other cosmetic sand.

Frequently Asked Questions
1. Do I need to rinse this aquarium substrate before adding it to my tank?
Yes, giving Controsand Vesuvius a quick rinse in clean tap water before placing it in your aquarium is recommended to remove loose lava dust from transit and ensure immediate water clarity.
2. How much substrate do I need for my aquarium size?
For foreground pathways or focal accenting, a single 3-liter bag covers most tanks up to 9 gallons. For full bed coverage or larger setups up to 20 gallons, an 8-liter bag provides plenty of volume to build depth.
3. Can I combine UNS Controsand Vesuvius with aquarium sand in the same aquascape?
Yes, combining decorative lava gravel with aquarium soil or cosmetic aquarium sand is a popular technique for high-impact aquascaping layouts. You can place aquarium soil in the rear or planting pockets for root growth and use Vesuvius lava gravel along hardscape borders or pathways for striking visual contrast.
