🏝️ MarcoRock Bahama Aragonite Sand

Natural Caribbean Beauty – The Ideal Reef-Safe Substrate for Your Aquarium

MarcoRock Bahama Aragonite Sand is the premium choice for aquarists seeking a clean, natural, and biologically balanced substrate for their marine or reef aquarium. Harvested responsibly from the pristine tropical waters of The Bahamas, this pure aragonite-based sand is both functional and beautiful. Its composition supports a stable pH, provides buffering capacity, and enhances the health of your aquarium ecosystem by creating a home for beneficial bacteria.

This high-purity aragonite sand is free of dyes, chemicals, and artificial additives. Its smooth texture and off-white to light beige coloration mimic natural reef environments, helping fish and invertebrates feel at home. It’s also the perfect grain size to remain visually clean while still allowing for burrowing behavior by gobies, wrasses, pistol shrimp, and other sand-sifting inhabitants.

📐 Grain Size & Appearance

MarcoRock Bahama Aragonite Sand typically ranges from 0.5mm to 1.5mm, which is ideal for most marine aquariums — not too fine to blow around under high flow, yet soft enough for digging and natural substrate interactions. Its smooth grains are easy on the gills and undersides of sand-dwelling fish like jawfish and gobies.

The sand’s naturally occurring off-white shade brightens your tank, enhances coral coloration through light reflection, and provides a more realistic ocean floor aesthetic. Whether you’re building a mixed reef, soft coral garden, or fish-only system, this substrate instantly uplifts the visual appeal of your scape.

🌱 Biological Boost

Aragonite’s calcium carbonate composition actively helps buffer aquarium water, reducing fluctuations in pH and promoting coral health. It also promotes biological filtration, supporting colonies of nitrifying bacteria that aid in natural waste breakdown and nutrient cycling. This is especially critical in new tank setups or bare-bottom tank conversions where added biological stability is needed.

⚖️ How Much Do You Need?

As a general guide:

• Use 0.75 to 1.5 kg per 10 liters of tank volume depending on desired sand bed depth
• Supplied in a convenient 10kg bag – perfect for starting or replenishing your reef or marine setup!
• For a standard 4ft (120cm) aquarium, 18–30kg typically provides a depth of 2.5–5cm

For deeper sand beds (e.g., for jawfish or burrowing shrimp), increase your substrate volume accordingly.
