Oceanic Corals is now sourcing a “new” Denitrification Pellet they call NpX Bio-Beads. Sporting the same size and shape as the NP Biopellets, Oceanic Corals claims that their NpX Bio Beads are sources from the same “trusted manufacturer”. Made of biologically degradable polymers, these pellets allow aerobic growth of bacteria which in turn is said consume nitrates and phosphates. Oceanic Corals states that denitrification will take about 2-3 weeks to “get up to full speed”, and that as an added benefit, colonizing bacteria will occur within the reactor only, and not on other surfaces and pumps. Beads are best used in a reactor where they are tumbled aggressively. A specific danger of oxygen level drops (during the initial introduction and subsequent algae bloom) is identified in the product guidelines, and as a pre-caution, users with high nutrient levels are instructed to discharge the reactor directly into the skimmer (for re-oxygenation).
