Fauna Marin doesn't publish a fixed ml-per-100L figure for this reason; instead, dial in fluoride using the Elementals Calculator at lab.faunamarin.de (which factors in tank volume and current KH) or via Trace 3 in the Balling Light system, and re-test with an ICP or dedicated fluoride kit before increasing the dose further.\u003c\/p\u003e\u003cp\u003eIncludes: 1x 1000ml bottle.\u003c\/p\u003e\u003cp\u003eCompatible with: Fauna Marin Balling Light Trace 3 and Color Elements Red also supply fluoride — check total fluoride input across your dosing regimen before adding this separately; dose via the Fauna Marin DIY Doser adapter.\u003c\/p\u003e","brand":"Fauna Marin","offers":[{"title":"Default Title","offer_id":46000586293292,"sku":"FM-EF-85","price":28.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/4382\/5196\/files\/fauna_marin_elementals_fluoride_1000ml_3.jpg?v=1787190001","url":"https:\/\/www.marineconceptsupply.com\/products\/elementals-f-fluoride-1000ml-fm-ef-85","provider":"Marine Concept Supply","version":"1.0","type":"link"}
