{"product_id":"black-java-rock","title":"Black Java Rock","description":"\u003cp\u003eBlack lava rock is one of the best hardscape materials for aquascaping because it is lightweight, highly textured, completely inert, and highly porous. Its rough, dark surfaces create a beautiful, high-contrast look when paired with bright green aquatic plants.\u003c\/p\u003e\n\u003cp\u003eBenefits of Black Lava Rock\u003c\/p\u003e\n\u003cp\u003eInert Nature: It does not alter your water chemistry or alter your pH levels, making it safe for sensitive shrimp and soft-water fish.\u003c\/p\u003e\n\u003cp\u003eBiological Filtration: The millions of tiny micro-pores inside the rock offer a massive surface area for beneficial nitrifying bacteria to colonize.\u003c\/p\u003e\n\u003cp\u003ePlant Anchoring: Its rough, sandpaper-like texture makes it incredibly easy to attach epiphytes like moss, Anubias, and Bucephalandra without them slipping off.\u003c\/p\u003e\n\u003cp\u003eLightweight Structural Building: Because it is less dense than traditional stones like Seiryu or Dragon stone, you can build massive, tall structures without adding too much heavy stress to your aquarium glass.\u003c\/p\u003e\n\u003cp\u003eStep-by-Step Layout Guide\u003c\/p\u003e\n\u003cp\u003eStep 1: Prep Rocks ➔ Step 2: Lay Base Support ➔ Step 3: Arrange Hardscape ➔ Step 4: Secure \u0026amp; Plant\u003c\/p\u003e\n\u003cp\u003ePrep the Rocks: Lava rock traps a lot of dust during transit. Scrub them thoroughly in a bucket of water to clean out the debris before putting them into your tank.\u003c\/p\u003e\n\u003cp\u003eProtect the Glass: Place a thin sheet of plastic grid (eggbricate) or a layer of basic volcanic gravel at the very bottom of the tank to distribute the weight and protect the bottom glass from sharp edges.\u003c\/p\u003e\n\u003cp\u003eCreate Depth: Slope your active soil or substrate from the front to the back of the tank. Stacking your largest \"main stones\" in the front-middle and smaller \"supporting stones\" toward the back creates a powerful optical illusion of depth.\u003c\/p\u003e\n\u003cp\u003eSecure and Glue: Use cyanoacrylate superglue gel combined with small pieces of tissue paper or cotton wool to firmly bond the lava rocks together so your structure never collapses.\u003c\/p\u003e\n\u003cp\u003eAdd Plants: Stuff mosses, ferns, and carpeting plants tightly into the natural cracks and crevices of the stone.\u003c\/p\u003e","brand":"Jasmin Aquatics Store","offers":[{"title":"Default Title","offer_id":53440861241641,"sku":null,"price":15.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/4325\/2521\/files\/Micro-Pellets_20260821_055131_0000.png?v=1787277133","url":"https:\/\/jasminaquaticsstore.com\/ar\/products\/black-java-rock","provider":"Jasmin Aquatics Store","version":"1.0","type":"link"}
