The dark colour enhances the vibrant colours of fish and plants while creating a more natural environment that helps shy species feel secure and display their best colours. The smooth, rounded grains are gentle on sensitive barbels, making this substrate an excellent choice for bottom-dwelling fish such as Corydoras, loaches, and catfish. The dark finish reduces light reflection, encouraging shy fish to behave naturally and display richer colours. \u003c\/p\u003e\n\u003cp\u003eJBL Sansibar Dark is ideal for planted aquariums, aquascapes, shrimp tanks, and community aquariums. The fine grain size provides excellent root support for aquatic plants while preventing waste and mulm from sinking deep into the substrate, making aquarium maintenance easier. The substrate is completely water-neutral, containing no harmful substances that could alter your aquarium's water chemistry. \u003c\/p\u003e\n\u003cp\u003eRinse the substrate thoroughly before use to remove any dust created during transport. Spread the substrate evenly across the base of the aquarium. For planted aquariums, use approximately 6–8cm of substrate or place JBL Sansibar Dark over a nutrient substrate such as JBL AquaBasis for enhanced plant growth.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAvailable in 5kg and 10kg bags\u003c\/li\u003e\n\u003cli\u003ePremium natural dark aquarium sand\u003c\/li\u003e\n\u003cli\u003eFine 0.2–0.6mm rounded grain size\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIdeal for planted aquariums and aquascaping\u003c\/li\u003e\n\u003cli\u003eGentle on Corydoras, loaches and other bottom-dwelling fish\u003c\/li\u003e\n\u003cli\u003eEnhances the natural colours of fish and aquatic plants\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWater-neutral – will not affect aquarium water chemistry\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Creature Culture","offers":[{"title":"10kg","offer_id":52893482221879,"sku":null,"price":53.99,"currency_code":"NZD","in_stock":true},{"title":"5kg","offer_id":52893503324471,"sku":null,"price":33.29,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/2415\/7239\/files\/ChatGPTImageJun27_2026_12_19_33PM.png?v=1782519584","url":"https:\/\/creatureculture.co.nz\/products\/bl-sansibar-dark-aquarium-sand-premium-natural-aquarium-substrate-10kg","provider":"Creature Culture","version":"1.0","type":"link"}
