Water-Parameter Friendly: UNS Controsand Sequoia aquarium substrate is formulated to remain inert in freshwater and planted aquariums, helping maintain stable water parameters and providing a balanced environment for aquatic life.
Earthy Mixed Pebble Gravel: With mixed pebble sizes of 6–15 mm, this earthy-colored fish tank gravel adds natural texture and depth to aquascapes, complementing driftwood, stones, and live plants.
Versatile for Aquascaping: This fish tank substrate adapts to a variety of aquascaping styles — from minimal nature setups to dense planted layouts — suitable for large aquariums, small fish tanks, and compact setups.
For Shrimp and Gentle Bottom Species: The smooth, rounded pebbles offer a comfortable surface for shrimp and bottom-dwelling fish, allowing natural movement and foraging in freshwater aquariums.
Ready to Use: Pre-washed for convenience, UNS Controsand Sequoia aquarium pebbles can be placed directly into your fish tank. A light rinse before setup removes residual dust and maintains water clarity.
