Another nitrate and phosphate reducing biopellet is available on the market now as Reef Dynamics adds NOPO BioPellets to its line of products. While there appears to be no major differentiators between the NOPO BioPellets and what else is on the market, the pricing and dealing with a preferred brand or vendor may be why you would chose one brand over another. Usage recommendations call for roughly 250ml per 50 gal. of aquarium water along with an efficient skimmer. For heavily stocked tanks, you may use more NOPO BioPellets along with standard GFO to keep phosphates in check. A well aerated media reactor should be used to give adequate dwell time for the bacteria as well as preventing the buildup of hydrogen sulfide gas (H2S). Reef Dynamics is selling the NOPO BioPellets in 250, 500 and 1000ml sizes ($29.95, $49.95 and $79.95 respectively) or if you need a massive quantity, you can get the 10kg container for $820. The NOPO BioPellets are available via the Reef Dynamics online store.
