It contains selected bacterial strains that speed up the breakdown of toxic organics and ammonia, greatly shortening the wait time on a new reef tank. Available in 10 ml and 50 ml.\u003c\/p\u003e\n\n\u003cp\u003eThe 10 ml format seeds several nano-to-mid tank volumes — the 50 ml is the economy format for larger tanks or regular use.

Bio S becomes useful again after a big water change, after a medication treatment that impacted the flora, or after moving the tank.\u003c\/p\u003e","brand":"Aquaforest","offers":[{"title":"10 ml","offer_id":38010902479019,"sku":"AF1256","price":13.99,"currency_code":"CAD","in_stock":false},{"title":"50 ml","offer_id":47580593750187,"sku":"AF1270","price":36.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0513\/7108\/1899\/files\/aquaforest-bio-s_2.jpg?v=1775860793","url":"https:\/\/reefsolution.com\/en\/products\/aquaforest-bio-s","provider":"Reef Solution","version":"1.0","type":"link"}
