Product Details
✓100% Natural Volcanic Rock: They are crushed & sifted for uniform 3‑6 mm(1/8-1/4 in) size. This inert volcanic material offers slowly‑released trace minerals, long‑lasting & reusable. Rinse dust before aquarium use
✓Great Drainage & Moisture Control: Porous lava rock drains fast, absorbs & releases moderate moisture. It reduces compaction & overwatering, lowering root‑rot risks for succulents, cacti & orchids
✓Versatile Top-Dressing & Soil Additive: Use as decorative top-dressing to beautify pots & suppress weeds. Mix with potting soil to boost aeration & drainage for succulents, cacti, and houseplants
✓Multi‑Purpose Indoor & Outdoor Use: Perfect for aquariums, terrariums, fire pits, garden soil amendment and DIY crafts. Durable rock withstands heat and varying weather for all‑season projects
✓Safe Aquarium Substrate: Inert lava rocks won’t alter pH, ideal for freshwater, shrimp, betta tanks & hydroponics, creating natural‑feeling habitats for aquatic life
