Explore decorative aquarium rocks, aquascaping stones and reef rock at The Tech Den Australia. Compare natural stone, shaped marine rock and rock-look ornaments for different aquarium layouts, alongside selected ceramic hides and pond décor.

Choose your aquascaping materials

• Natural aquarium stones: Browse Aqua Natural Seiryu, Dragon, Rosy Cloud and lava rock, Aqua Premium White Aurum, Texas Holey Rock, Dymax decorative stones and selected spawning stones. Compare textures, colours, piece sizes and pack weights.
• Marine and reef rock: Explore Carib Sea Life Rock base, shapes, shelves, branches, arches and tree kits, Java Reef Rock, Aquaforest Synthetic Rock and Dalua Marco foundation and shelf options. Match the individual material to your aquarium's intended use and water chemistry.
• Rock-look ornaments: Aqua One Basalt Rock ornaments and Pet Worx preformed resin aquascapes offer alternatives to loose natural stone. Aqua One Copi coral ornaments are decorative replicas, not live coral.
• Related décor and supplies: This collection also includes aquavitro ceramic hides, Juwel Deco Stone décor, Jurassic decorative stones, URS Frog Rocks, Dalua frag-mount rubble and aquascaping powder. PondMAX rock-look ponds, cascades and spillways are separate water-garden products.

Check size, material and water chemistry

Allow space for livestock, equipment and maintenance when planning your layout. Natural pieces vary in shape and colour, and illustrative images may not show the exact piece supplied. Check whether the listing is priced per piece, per 100g, by bag or as a complete box or kit.

Rock types are not interchangeable. Check preparation instructions and the material's effect on pH and hardness before adding it to your aquarium. The Dalua Marco Nano Shelf listing specifically notes that it raises pH in freshwater. Do not assume every stone is chemically neutral or suitable for every fish, shrimp or planted tank.

For reef layouts, follow product-specific preparation and aquarium-cycling guidance rather than assuming new rock makes an aquarium immediately ready for livestock. Check the recommended adhesive and curing instructions when assembling rock structures; aquascaping powder is a separate construction supply.

Pickup and delivery conditions

Many loose-rock listings, Java Reef Rock pieces, larger arches and selected PondMAX products are in-store pickup only. Other bags and boxes carry additional bulky or heavy-item delivery charges. Check the individual listing for purchasing conditions, regional restrictions and delivery costs before ordering.
