DrTim's Aquatics NP-Active Pearls offer a novel and innovative solution for controlling unwanted nitrate and phosphate levels in saltwater aquariums. These pure, biodegradable bio-polymers provide an ultimate carbon source, fostering the growth of beneficial bacteria that naturally consume and reduce these nutrients, leading to a healthier and more stable reef environment. Specially developed for aquariums, these pearls are safe for all fish and corals and work effectively in all aquarium setups. They are a pure product with no fillers or harsh chemicals, offering an easier alternative to traditional carbon dosing methods. Certified Marine Biodegradable by ASTM D7081 and proudly made in the USA, NP-Active Pearls should be placed in a reactor for constant tumbling and oxygenation, with a good protein skimmer recommended for optimal results. Initial seeding may take 2 to 4 weeks, and the pearls will be consumed over time, requiring replenishment. This product is ideal for reef aquarists seeking an advanced, hands-off approach to nutrient export and water quality management. Its ease of use, safety for sensitive inhabitants, and environmentally conscious biodegradable composition make it a premium choice for maintaining pristine water parameters, especially for those who value American-made, high-quality filter media.
