It supports optimal KH levels for freshwater planted aquariums. Although ideally suited to planted aquaria, it may be used in any aquarium environment. Onyx Sand� is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Onyx Sand� is not chemically coated or treated, and as a carbonate rich sand, it has a slight buffering capacity that may raise pH by 0.1 - 0.5 pH units (depending on source water characteristics). Onyx Sand� is good for the life of the aquarium and need not be replaced.\u003c\/span\u003e\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"3.5kg","offer_id":46089959670005,"sku":"3503","price":31.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/9818\/4437\/files\/onyx-sand.jpg?v=1753331144","url":"https:\/\/aquateesfishland.com.au\/products\/seachem-onyx-sand-substrate-3-5kg","provider":"AQUATEES FISHLAND","version":"1.0","type":"link"}
