Run them in a dedicated biopellet reactor with enough flow to keep the pellets gently tumbling — stagnant pellets stop working and can foul the water instead of cleaning it. Start with a conservative amount, then increase gradually while monitoring NO3, PO4, and livestock response over the first several weeks.\u003c\/p\u003e\u003cp\u003eCompatible with: Reef Octopus BR70, BR110, and BR1000SS biopellet reactors (reactor sold separately).\u003c\/p\u003e","brand":"Reef Octopus","offers":[{"title":"Default Title","offer_id":45973527035948,"sku":"CV-BP1882","price":94.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/4382\/5196\/files\/biosphere_closeup_3_85c3af11-bdab-449e-b1ab-5fc9201b97ea.jpg?v=1786980286","url":"https:\/\/www.marineconceptsupply.com\/products\/biosphere-bio-pellets-1-2-gallon-bulk-cv-bp1882","provider":"Marine Concept Supply","version":"1.0","type":"link"}
