OceanSix Crystal Reef is a blend of organic carbon molecules and amino acids designed to reduce algae-promoting nutrients like nitrate and phosphate by supporting nutrient-reducing heterotrophic bacteria. This helps maintain a balanced bacteria population, promoting nutrient control without impacting corals' Zooxanthellae. Crystal Reef acts as a complete carbon source for denitrifying bacteria.
