Each piece of rubble is carefully sized between 20 mm and 50 mm, making it perfect for use in sumps, refugiums, and biological filter chambers where efficient water flow and bacterial colonisation are essential.\u003c\/p\u003e\n\u003cp\u003eComposed entirely of natural coral and aragonite, this rubble is rich in calcium and carbonate, helping to buffer pH, stabilise alkalinity, and support coral and invertebrate growth. The irregular texture and porous surface provide extensive area for beneficial bacteria, promoting strong nitrification and denitrification processes to maintain balanced, crystal-clear water.\u003c\/p\u003e\n\u003cp\u003eIn addition to its filtration benefits, Bioscape Coral Rubble can also be used as decorative rockwork, base rock for reef aquascaping, or in African cichlid aquariums to enhance water hardness and replicate natural habitats.\u003c\/p\u003e","brand":"Bioscape","offers":[{"title":"Default Title","offer_id":44209463754840,"sku":"15854","price":34.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/8557\/1672\/files\/Bioscape_Coral_Rubble_Bag_20-50mm11_e72daf0c-ca70-41bc-b28e-8f07980293b3.jpg?v=1780985242","url":"https:\/\/bespokeaquariums.com.au\/products\/bioscape-coral-rubble-5kg-bag-20-50mm-diameter","provider":"Bespoke Aquariums","version":"1.0","type":"link"}
