ATI Fiji White Sand 9KG
ATI Aquaristik has recently released their new Fiji White Sand onto the European market, and it’s not the typical calcium carbonate substrate found filling most saltwater aquaria in the hobby these days. Instead, this high purity sand is composed of 99.6% pure calcium and magnesium, and is said to be one of the cleanest substrates on the market today. In addition to being clean, the sand’s bright white colouration is also very reflective, bouncing diffuse light back up into the water column and providing more illumination to your corals. The reflected light will not be intense by any means, but it will undoubtedly provide more light energy to the undersides of corals, which often lose coloration as the branches above become more densely packed.

FAQ
What makes Fiji White Sand different from other aquarium substrates?
Fiji White Sand is composed of 99.6% pure calcium and magnesium, making it one of the cleanest substrates available. Its bright white color reflects diffuse light back into the water column, enhancing illumination for corals, especially those on the undersides.
Is this sand suitable for all types of saltwater corals?
The sand is specifically designed for saltwater aquariums and provides improved lighting conditions for corals. However, compatibility may vary depending on coral species and tank setup. Please consult with a marine biologist or experienced aquarist for specific recommendations.
How does the reflectivity of the sand benefit coral health?
The white coloration reflects diffuse light upward, increasing light exposure to the undersides of corals. This helps prevent color loss in densely packed coral branches that otherwise receive insufficient light.

Sophie Mills –
I’ve used this sand in my 120-liter reef tank for three months now. The white color really enhances the lighting in the tank, especially for the lower parts of my Pocillopora and Acropora corals. The sand feels clean and doesn’t clump. No issues with algae growth so far. Very satisfied with the product.
Gordon Thomson –
The sand is very fine and easy to mix into the substrate. I noticed a noticeable improvement in the coloration of my soft corals after a few weeks. It’s a bit more expensive than regular sand, but the quality and light reflection justify the cost.
Deirdre Howard –
After switching from a standard calcium carbonate substrate, my tank has become more vibrant. The light reflection from the white sand helps even out the lighting across the tank. No settling or compaction issues observed after six weeks.
