Unlike traditional substrates that break down over time, Flourite Black never softens, degrades, or requires replacement—remaining effective for the lifetime of your aquarium. Its deep black tone enhances the rich greens and reds of living plants while creating a high-contrast backdrop that highlights the natural colors of your fish and invertebrates. Safe for all freshwater ecosystems, it contains no chemical coatings and will not alter your tank's pH parameters.\u003c\/p\u003e\n\u003ch3\u003eQuick Reference \u0026amp; Requirements Table\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRequirement \/ Specification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eAvailable Sizes\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e3.5 kg (7.7 lbs), 7 kg (15.4 lbs)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eSubstrate Type\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003ePremium porous clay gravel\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eAquarium Compatibility\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eFreshwater planted aquariums, community tanks, shrimp setups\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eWater Chemistry Impact\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eChemically inert; will not alter pH or Carbonate Hardness (KH)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eLifespan\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003ePermanent (never needs replacement or topping up)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Seachem","offers":[{"title":"Flourite Black 3.5 kg","offer_id":56742952403284,"sku":"FB3723","price":24.63,"currency_code":"EUR","in_stock":true},{"title":"Flourite Black 7 kg","offer_id":56742952436052,"sku":"FB3725","price":40.74,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1052\/5828\/7444\/files\/flourite-black.jpg?v=1786269742"},{"product_id":"seachem-flourite-black-sand","title":"Seachem Flourite Black Sand","description":"\u003cp\u003eCreate a thriving, natural aquascape with \u003cb\u003eSeachem Flourite Dark\u003c\/b\u003e.
