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. Kona is a rounded pebble aquarium gravel featuring deeper earthy tones that bring rich, natural contrast to riverbed displays or tumbled paths. Its smooth granule texture provides a foraging ground for Corydoras, dwarf shrimp, and other bottom dwellers without harsh or sharp edges. Measuring between 3mm and 5mm, this versatile substrate works beautifully on its own, blended with finer cosmetic sand, or placed along transition zones for extra visual depth.
