Caribsea Aquarium Substrates:
Aragonite composition provides pH support in the anaerobic conditions necessary for denitrifying bacteria.
Provides calcium and carbonate in the natural proportions which are utilized by hard corals and clams.
Superior trace element composition & precision grading for maximum pore water space allows easier diffusion of calcium, carbonate, and trace elements, even in deep sand beds.
Strongest pH support and buffering capability of any substrate. Aids in maintaining ocean values of carbonate hardness.
Pure and safe: Not beach or reef collected. No metal, pesticide residues, petroleum or other harmful organics & NO SILICA.
Do not settle for cheaper industrial grades of aragonite! All of Caribsea's substrates go through acid washing (to remove surface organics which can pollute your aquarium), and pass through rare earth magnets that remove all metal (yes metal! - which can cause undesirable algae growth) fragments from the sand. |
