CaribSea Arag-Alive!™ Fiji Pink Live Sand
CaribSea’s Arag-Alive!™ contains a broad spectrum of marine bacteria, including specially selected strains, to accelerate the establishment of a healthy biological filter in new aquariums. It helps reduce initial ammonia spikes and speeds up the cycling process, making it safer and more efficient. The substrate creates a natural biological balance, allowing live rocks and most invertebrates to be added immediately. Fish should be introduced gradually after the first 3 weeks, with no more than one inch of fish per 5 gallons during this period.

The sand settled well in my 55-gallon tank. I added live rocks right away and noticed a steady drop in ammonia levels within the first week. My shrimp and snails are thriving. Great for beginners looking to speed up cycling.
Sam Baker –
Fiji Pink looks nice in the tank. The sand is fine and easy to work with. I used it in a reef tank with corals and it didn’t cause any issues. Fish were added after 3 weeks as recommended.

This product helped my new tank cycle much faster than expected. No ammonia spikes, and the biological balance was established quickly. I’m very satisfied with the performance.
