Nature's Ocean Bio-Activ Live Aragonite Reef Sand
Cycle your tank and add fish on the same day with Bio-Activ Live Aragonite substrate. Collected directly from the ocean bottom, this natural substrate contains live bacteria for controlling nitrate. Aragonite also provides essential inorganic elements like strontium, cobalt, and zinc, and helps to maintain tank pH. Digger friendly, and completely safe for sand-sifting organisms. There's no waiting, just add fish! Gravel and substrate color may differ or vary due to your computer monitor's resolution.
