* Natural aragonite substrate for marine and reef aquariums
* Unique spherical substrate reduces injury to burrowing fish
* Porous substrate provides maximum surface area for biological filtration

Spherical aragonite substrate ideal for saltwater fish and invertebrate aquariums. Reef Base consists of naturally occurring reef spheres mixed with aragonite coral chips. Together, they maintain a stable pH and a high buffering capacity even over extended periods of time. Porous Reef Base spheres also provide a large surface area for bacteria colonization, functioning as an excellent media for both aerobic (nitrifying) and anaerobic (denitrifying) biological filtration. Spheres are up to 2 mm in size.

Reef Base Substrate provides the following benefits:

Maintains proper pH with high buffering capacity
Contains aragonite - the most dissolvable form of calcium carbonate
Natural porous structure provides maximum surface area for biological filtration
Smooth “sphere” shape reduces damage to burrowing invertebrates or jawfish.
Free from harmful impurities including nitrate and phosphate
Pre-washed so only minimal washing is required prior to use
