The size of each piece varies from 1cm to 6cm in size, so is quite a large size meaning it can be used in most external filter trays or sump tanks.
Crushed coral is a natural pH buffer, and will help to buffer the water to a pH of 8.2-8.3. It will also help to buffer GH and KH levels.
When using as a bio-media, we recommend using around 100g per 100 litres of water.
