Product Information

Well known for their expertise with all things aquatic, TMC Coral Gravel is an ideal substrate that not only provides a good base for your tank, but also supports healthy filtration.

The gravel has been graded to give a great colour, and is available in various sizes from 4mm to 10mm.

The highly porous structure of this gravel provides the ideal level of biological filtration, as friendly bacteria can form easily. As it has a large surface area this makes it a great way to bolster the filtration for a healthy and clean tank.

This gravel will not compact like other types of gravel, and it has a high buffering value which makes it ideal for marine aquariums and freshwater set ups which require a higher pH value.

This excellent gravel is available in the following formats:

  • 4kg of Fine Gravel - 4mm in size
  • 4kg of Medium Gravel - 6mm in size
  • 4kg of Coarse Gravel - 10mm in size
