{"title":"Marine Substrates","description":"\u003cp\u003eMarine substrates include sands, gravels and crushed coral mixes that form the base of your saltwater aquarium, affecting both the look and the biology of the tank. The right substrate helps house beneficial bacteria, supports burrowing fish and invertebrates, and in some cases can also help buffer pH. Fine sands are ideal for wrasses and sand-sifters, while slightly coarser options suit higher flow or more robust livestock. Whether you’re aiming for a clean, white reef floor or a more natural, mixed-grain look, choosing an appropriate marine substrate is key to both the aesthetics and long-term stability of your system.\u003c\/p\u003e","products":[],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0543\/0391\/6205\/collections\/Marine_Substrates.png?v=1771948617","url":"https:\/\/aquagroup.co.uk\/collections\/marine-substrates.oembed","provider":"Aqua Group","version":"1.0","type":"link"}
