Coral Sand Remineralising Media

This coral sand remineralising media can be used in our refillable remineraliser and alkaliser cartridges to help raise the pH of post-RO water and add natural mineral content back into the water.

Suitable For

This media is suitable for use with our refillable remineraliser alkaliser cartridges, including:

Important Usage Note

Please note: This coral sand should generally not be used on its own. For best results, it is preferably used together with calcite or inside a suitable refillable remineraliser/alkaliser cartridge. Results will vary depending on the incoming water quality, contact time and cartridge setup.

How It Works

This aragonite-based coral sand can help increase the pH of post-reverse osmosis water, with final pH levels varying depending on the infeed pH of the water supply and the system configuration.

In some applications, post-RO water may increase up to around pH 10, although actual results will vary.
