Its unique composition raises mineral content and slightly enriches the water — providing a beneficial mineral supplement for plants while maintaining a neutral to slightly alkaline pH. Onyx Sand has a distinct dark pebbled appearance that works beautifully in heavily planted and hardscape aquariums. Like all Seachem Flourite substrates, Onyx Sand is permanent and never needs to be replaced.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNaturally raises mineral content — supplements plant nutrition\u003c\/li\u003e\n\u003cli\u003eNeutral to slightly alkaline pH — suits a wide range of planted setups\u003c\/li\u003e\n\u003cli\u003eDark, natural pebbled appearance — suits planted and hardscape tanks\u003c\/li\u003e\n\u003cli\u003ePermanent substrate — never needs replacement\u003c\/li\u003e\n\u003cli\u003epH neutral — will not adversely affect water chemistry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAvailable in 7.7 lb and 15.4 lb sizes.\u003c\/p\u003e","brand":"YoCamron's Aquatics","offers":[{"title":"7.7 lbs","offer_id":50095463694573,"sku":"SEACHEM-ONYX-7LB","price":12.77,"currency_code":"USD","in_stock":true},{"title":"15.4 lbs","offer_id":50095463727341,"sku":"SEACHEM-ONYX-15LB","price":22.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0806\/1032\/8813\/files\/B67CAC9A-AAD3-4C0F-BC73-835A22B5A649.jpg?v=1781662768","url":"https:\/\/yocamronsaquatics.com\/products\/seachem-onyx-sand-planted-aquarium-substrate","provider":"YoCamron's Exotics","version":"1.0","type":"link"}
