Product Description
Create a thriving marine environment with Carib Sea Arag-Alive Bahamas Oolite Aquarium Sand. This premium, aragonite-based live substrate is specifically engineered for reef tanks, marine setups, and specific cichlid aquariums. Each 10-pound bag comes pre-inoculated with millions of beneficial marine-specific bacteria, which are essential for suppressing New Tank Syndrome and accelerating the natural nitrogen cycle. By introducing these active biological components, you can safely add your favorite invertebrates sooner while ensuring a more stable ecosystem from the start.
The Bahamas Oolite texture features an ultra-fine, smooth grain size, making it the perfect choice for shallow sand beds and bottom-dwelling fish species like gobies, wrasses, and rays. Because it is composed of natural aragonite, the sand acts as a functional buffer, naturally supplying calcium, carbonate, and essential trace elements that help maintain a consistent, healthy pH level of 8.2 in your saltwater setup. This authentic USA-imported product offers an aesthetic bright white finish, giving your aquarium the professional, natural look of a tropical beach. Designed for ease of use, it helps clarify aquarium water quickly, providing a visually stunning and biologically balanced home for your marine life.
FAQ
Q1. Can you use CaribSea Arag-Alive in a freshwater aquarium?
Ans: No, this product is specifically designed for marine, reef, and hard-water cichlid aquariums. Because it is made of aragonite, it will naturally increase and buffer your water pH, which is typically not suitable for standard community freshwater tanks.
Q2. What is the benefit of aragonite sand?
Ans: Aragonite sand is highly valued in reef keeping because it naturally buffers the water, helping to keep pH stable at 8.2. Additionally, it slowly dissolves to release calcium and other trace elements that are essential for the health of corals and other calcifying marine organisms.
Q3. Does this sand help cycle my tank faster?
Ans: Yes, because this is 'live' sand that is pre-seeded with millions of beneficial bacteria, it significantly reduces the time required for a new tank to cycle. It helps handle the initial ammonia spike, allowing for a faster and safer introduction of fish and invertebrates.
Q4. Is this product authentic and imported from the USA?
Ans: Yes, all Carib Sea products sold at Rudra Retails are 100% authentic and sourced directly from USA distributors. We ensure you receive the same high-quality substrate used by professional aquarists globally.
Q5. How deep should I layer the oolite sand?
Ans: Due to its fine grain size, it is ideal for shallow sand beds, where even a depth of 1 inch can be highly effective for denitrification. If you prefer a deeper sand bed, it is often recommended to mix or cap it with a slightly coarser sand to ensure stability in high-flow aquariums.
