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. Buying in this bulk case is the most economical way to keep several reactors topped off on a rolling 3-month schedule. Start with a conservative amount on any new system, then increase gradually while monitoring NO3, PO4, and livestock response.\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":45973527068716,"sku":"CV-BP18820","price":734.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/4382\/5196\/files\/biosphere_closeup_3_82b5244a-e46b-401e-8ab6-8722c160ba88.jpg?v=1786980286","url":"https:\/\/www.marineconceptsupply.com\/products\/biosphere-bio-pellets-5-gallon-bulk-cv-bp18820","provider":"Marine Concept Supply","version":"1.0","type":"link"}
