Dragon stone is marketed and sold as a freshwater aquascaping stone — Bioscape doesn't publish marine or reef-tank guidance for it, so we're not making that claim here.\u003c\/p\u003e\n\u003ch3\u003ePreparation\u003c\/h3\u003e\n\u003cp\u003eScrub and rinse every piece under running water until it runs clear before it goes in the tank. The crevices trap clay dust and quarry sediment, and a jet of water through the holes clears far more than a quick dunk. The stone itself is inert, but organic matter and dust left unwashed in the pockets can affect water clarity and pH in the first weeks.\u003c\/p\u003e\n\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\n\u003cp\u003eOnce established, dragon stone needs no ongoing treatment. Avoid chemical cleaners on it during routine maintenance, and avoid heavy scrubbing once biofilm and moss have established — that patina is part of what gives an aged aquascape its look.\u003c\/p\u003e\n\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\n\u003cp\u003eCovered against being not as described under Australian Consumer Law. As a natural product, the exact pieces you receive will vary from the listing photo in shape, colour and size split — that's expected, not a fault. This is a 15 kg box, so factor the weight into how you plan to carry and place it.\u003c\/p\u003e\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\u003ch4\u003eWill 15 kg be enough for my tank?\u003c\/h4\u003e\n\u003cp\u003eIt depends on the scale of the structure and how dense a look you want. Bioscape doesn't publish a coverage figure for this box, but as a general guide, one box comfortably builds a full hardscape in a small-to-medium tank; a large tank or a dense, multi-layered layout often uses two or more boxes.\u003c\/p\u003e\n\u003ch4\u003eWill this raise my water hardness?\u003c\/h4\u003e\n\u003cp\u003eNo, not directly — dragon stone is inert and doesn't shed minerals into the water. Any pH movement usually comes from sediment or organic matter trapped in the crevices, which thorough rinsing before use largely prevents.\u003c\/p\u003e\n\u003ch4\u003eIs it safe for shrimp and soft-water fish?\u003c\/h4\u003e\n\u003cp\u003eYes. Unlike calcareous rock, dragon stone doesn't push hardness up, which makes it a common choice for shrimp tanks and soft-water planted setups.\u003c\/p\u003e\n\u003ch4\u003eCan I buy fewer pieces instead of the full 15 kg?\u003c\/h4\u003e\n\u003cp\u003eYes — see Dragon Rock above, sold as a single piece, if you only need to top up an existing scape.\u003c\/p\u003e","brand":"Bioscape","offers":[{"title":"Default Title","offer_id":54774341271843,"sku":"ROCK01","price":162.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/bioscape-dragon-rock-15kg-bo-43876774052131.webp?v=1790239540","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/bioscape-dragon-rock-15kg-box","provider":"Nicks AOT","version":"1.0","type":"link"}
