Live Reef Sand for New Aquariums, Fiji Pink 0.5–1.5 mm Substrate with Live Bacteria, in 10 or 20 lb Sizes

Give a new reef aquarium a biologically active foundation with Fiji Pink live reef sand. Its popular medium-to-large grain and attractive appearance create a welcoming base for a thoughtfully planned reef environment.

This sand contains millions of live bacteria that assist with faster cycling, making it especially useful for new aquarists and fresh reef setups. It also clears quickly, so you can spend less time waiting for the tank to settle.

Key Features

• Live bacteria support a faster aquarium cycle, giving a new reef setup an active biological starting point.
• The sand clears quickly after placement, reducing the wait before you can see and assess the aquascape clearly.
• A high amount of available surface area gives beneficial bacteria ample room to grow and thrive.
• Its 0.5–1.5 mm grain provides smaller particles suited to many fish and invertebrates that burrow or sift, though each species’ needs should be checked.
• By supporting a faster cycle, the live bacteria can contribute to less nuisance algae during the aquarium’s early stages.
