Jura Limestone pH Control

Drinking water quality natural microcrystalline exceptionally pure Calcium Carbonate (CaCO3) with low silica content.

Use as a coral look-alike substrate with excellent buffering qualities or as a sacrificial media. The stone dissolves very slowly providing for the remineralisation of soft waters. Suitable for aquarium, natural pond, swimming pool and potable water filters.

This gravel has been washed, kiln dried and graded.
