Somelite® (BL/SL)

Coral Granule Water Treatment Agents

Somelite® (BL/SL) – Product Overview

The natural coral grains used in this product are harvested from the beautiful ocean off semi-tropical Okinawa.
Also known as coral sand, this product is composed primarily of the shells and skeletons of reef-building coral and Foraminifera, such as star sand, that inhabit the area.
To form their shells and skeletons, these organisms ingest minerals – mainly calcium and magnesium – from the ocean.
As a result, coral sand is constituted mainly (approx. 95%) of calcium carbonate.
However, it also contains abundant amounts of many minerals – calcium, magnesium, etc. – that people need from their daily meals in order to be healthy.

When coral sand is used as a water-purifying agent, its minerals flow into the water, creating mineral water with a balance of minerals.
At the same time, it turns acidic tap water slightly alkaline and removes the bleachy odor.
As coral sand is a porous substance with innumerable minute holes of 10 µm or less, it also traps and removes foreign matter.
