Royal Nature Cultured Reef Rock (10kg Boxes)

Categories: ,

Product Description

Royal Cultured Reef Rock is a hand-made reef rock made of natural components; the same composition of materials found in nature. Unlike other ceramic rocks, Royal Reef Rock is very light weight and easy to work with. Special attention was taken to make sure this rock will have the highest porosity and pure materials without any Phosphates or Silicates.

Due to the super high-tech process, Royal Reef Rock is the closest match to the real natural reef rocks. Because of its super porosity, the rock can be used as a filtration medium for aerobic and anaerobic bacteria. The ease of colonization by beneficial microorganisms significantly shortens the maturation of the aquarium, especially while using Royal Nature probiotic salts.

The set contains rock plate shelves, arches and pyramids. The rock-by-rock hand manufacturing process of Royal Reef Rock ensures the uniqueness of each set, as well as providing a unique shape to each rock.

Royal Reef Rock is free from harmful nutrients, compounds or any toxic metals. It’s completely safe to use in any reef tank and increases the biological filtration in the aquarium. The final result of Royal Reef Rock comes out as a natural red coralline algae color for a perfect setup start and will be a perfect environment for real coralline algae. Royal Reef Rocks can be used in both marine water and fresh water environments.
