Fiji White Sand Small 0.3 - 1.2 mm (20 lbs) - ATI

Give your reef tank the clean, ultra-bright foundation it deserves with ATI Fiji White Sand. Sourced as a highly pure natural material, this premium substrate is engineered to meet the demands of high-energy SPS systems and diverse community reef tanks alike.

With an unmatched purity level and an ultra-white aesthetic, Fiji White Sand delivers both stunning visual appeal and crucial biological support for your marine ecosystem.

Why Choose ATI Fiji White Sand?

• 99.6% Pure Calcium & Magnesium: Composed almost entirely of pure calcium and magnesium compounds, this substrate is free from the unwanted organic and mineral impurities often found in lower-grade sands. It’s one of the cleanest, safest options available for sensitive coral reefs.

• Maximum Light Reflection: The brilliant, snowy-white color of this sand does more than just look pristine—it highly reflects your aquarium lighting. This creates a brighter overall tank and provides essential diffuse, reflective light to the undersides of your corals, mimicking natural reef environments.

• High Density, Low Drifting: Unlike typical light aragonite sands that blow into frustrating dunes, ATI Fiji White Sand features a significantly higher density. Being heavier, it stays firmly in place even under the high-turnover wavemakers and flow patterns required by modern reef tanks.

Find Your Perfect Grain Size

ATI Fiji White Sand is available in 20 lb (9.07 kg) bags across three distinct grain sizes to perfectly match your flow rates and livestock needs:

1. Small (S) | 0.3 – 1.2 mm

• Best For: Natural lagoon aesthetics, wrasses, sand-sifting gobies, jawfish, and other burrowing invertebrates.

• The Feel: A beautiful, fine-grain sand that gives a classic, untouched reef look while remaining soft enough for delicate belly-dwellers and sand-sifters.

2. Medium (M) | 1.0 – 2.0 mm

• Best For: The ultimate all-around reef substrate.

• The Feel: A versatile, universal grain size. It’s heavy enough to resist moderate-to-high flow settings while still offering a comfortable habitat for sand-dwelling tank inhabitants.

3. Large (L) | 2.0 – 3.0 mm

• Best For: High-energy SPS tanks, bare-bottom looks with substrate benefits, and extreme flow environments.

• The Feel: A coarser, heavy-duty grain designed specifically to handle powerful wavemakers and high-volume return pumps without shifting or blowing away.

How to Use & Preparation

To ensure a crystal-clear startup, follow these simple guidelines:

1. Rinse Thoroughly: Because it is a natural product, minor dust can accumulate during transit. Rinse the sand thoroughly in a bucket with clean water several times before placing it into the aquarium until the water runs mostly clear.

2. Recommended Depth: For an optimal biological balance and aesthetic, we recommend a bed depth of approximately 2 cm (approx. 0.8 inches).
