Bioscape Natural Coral Rubble 10kg 20-50mm Marine Aquarium Rock

Bioscape Coral Rubble 10kg (20–50mm) is natural marine coral rock ideal for use in reef aquariums, marine sump systems and biological filtration setups. The irregular shapes and porous structure provide an excellent surface area for beneficial bacteria to colonise, helping support a stable and healthy aquarium ecosystem.

This coral rubble is commonly used in sump chambers, refugiums and filter media baskets where additional biological filtration is required. The natural calcium carbonate composition also helps support marine aquarium stability and is suitable for both reef and fish-only marine systems.

With pieces ranging between 20mm and 50mm, the rubble size is ideal for stacking within filtration compartments or creating natural aquascaping features. It can also be used to stabilise live rock structures or provide hiding spaces for small marine animals.

Supplied in a convenient 10kg bag, Bioscape Coral Rubble is a versatile addition for marine hobbyists looking to enhance filtration, support beneficial bacteria and create a natural reef environment.
