More From TMC
TMC coarse grade coral gravel, also known as tropical marine gravel is a natural aragonite carefully graded to obtain a uniform grain size (5-10mm) and colour. It has a highly porous structure which makes it suitable for biological filtration, especially when used in conjunction with mechanical filtration.
It is suitable for using as a substrate in marine aquariums or freshwater aquariums where a high pH is required.
4kg will cover a 30cm x 30cm area to a depth of 3-4cm.
Coral gravel is currently only available for collection and payment in store.
