Ultum Nature Systems Controsand Tahoe (3L) is a natural, decorative aquarium gravel consisting of smooth, rounded pebbles in neutral tones. It is designed for freshwater aquariums, planted tanks, terrariums, and paludariums.

Key Specifications:

• Grain size: The pebbles measure approximately 3 to 5 mm.
• Appearance: It features a blend of earthy grey, tan, and white river-style pebbles that darken and show richer contrast when submerged.
• Water chemistry: Tahoe Controsand may increase water hardness.
• Livestock safety: Its smooth, rounded edges make it safe for shrimp and bottom-dwelling fish that forage through the substrate.

Usage & Preparation:

• Preparation: Rinse the gravel thoroughly with water before placing it in your tank to remove any fine dust from transit.
• Aquascaping: You can use it as a standalone substrate layer, a decorative riverbed accent, or mixed with finer sands and nutrient-rich soils.
