Description

You can now bring the world's most exotic reefs into your home with CaribSea's Arag-Alive substrates. It is developed from CaribSea's cooperation with public aquariums and zoological parks, where authenticity is a must. Arag-Alive helps maintain a proper pH for the life of your aquarium without the constant addition of chemicals, and creates a biological balance to discourage nuisance algae. Arag-Alive contains millions of bacteria per pound specially engineered for aggressive waste reduction in closed systems like your aquarium. Arag- Alive is engineered to suppress “new tank syndrome” and compress the ammonia cycle. It begins to cycle your aquarium instantly. In fact, independent labs prove Arag-Alive cycles your aquarium days faster than other brands.

  • Perfect for Mix Reef Tank
The sand is so beautiful. You can see the pink colors. And it won’t blow away easily. I got one bag for my 25g Innovative Marine Fusion Lagoon 25g. It’s about 1/2”- 3/4” in most parts, in some areas It’s about 1”- 1 1/4”. The Diamond Orange Goby can shift it with no problem. But the Two dot Goby is spitting the bigger size and the smaller or finer sands goes out it’s gills. Hope this can help. ... show more

  • Really nice!
It’s a mixed bag of what looks to be crushed coral with crushed rocks and sand. It’s really nice to look at and reflect tons of light back up. Really happy with this substrate!

  • Looks like crushed concrete/drywall. So perfect if you are looking for that
good looking, cleared up over night, just add the biomagnifier to it.
