DrTim's Aquatics NP-Active Pearls offer an innovative and simple solution for controlling nitrate and phosphate levels in your aquarium. This filter media utilizes pure, biodegradable bio-polymers that act as a solid carbon source for beneficial bacteria. As these bacteria consume the pearls, they also consume nitrates and phosphates from the water column, effectively reducing unwanted nutrients and promoting a healthier, cleaner aquatic environment for all fish and corals.

Made in the USA, these pearls are crafted from PURE, ASTM D7081 certified marine biodegradable material, containing no fillers or harmful chemicals. For optimal performance, NP-Active Pearls must be used in a media reactor to ensure they are constantly tumbling and well-oxygenated. A high-quality protein skimmer is strongly recommended to efficiently remove the bacterial biomass that is produced. The pearls are consumed over time and will require periodic replenishment to maintain their effectiveness.

This product is ideal for the reef aquarist seeking a reliable, low-maintenance method for nutrient reduction that is simpler than daily liquid carbon dosing. It is particularly beneficial for hobbyists with heavily stocked tanks or those struggling with persistent high nitrate and phosphate readings. For best results, users should have a media reactor and an efficient protein skimmer integrated into their system to fully leverage the benefits of this advanced filtration method.
