0.4-0.8mm Black Aquarium Sand, 3lbs Substrate for Fish Tank, Garden | Black Fish For Sale

• Reusable Aquarium Sand: Premium silica sand in 0.4-0.8mm. No toxins, no impurities, low dust. Rounded grains are gentle on delicate fins and bottom dwellers. Reusable and washable. Washes clean without fading – ideal for long-term use in aquariums and potting
• Substrate & Base Layer: This fish tank substrate forms a stable base where fish waste settles without clouding water. Even grain size supports aquatic plant roots. Rinsed and odor-free, it helps maintain cleaner tanks with less maintenance. Great for both freshwater and saltwater setups
• 3 Colors Available: Choose from Black (high contrast), White (bright modern), or Beige (warm biotope) fine sand. Mix and match for custom patterns and depth. Also great as a decorative top dressing for potted plants – prevents soil spillage while adding a clean, polished look
• Versatile Decor: Ideal as aquarium substrate, creating a beautiful and natural-looking underwater landscape for fish and plants. Use as terrarium base, reptile substrate, or aquatic plant medium. Also accents succulents, potted plants, tabletop fire pits, vase fillers, candle holders, crafts, and home decor
• How to Use: Rinses clear in 2-3 washes. Gently rinse, then add to tank, and pour water slowly along the glass wall. Slight cloudiness is normal initially – fine particles suspend temporarily. Wait 1-2 hours, they settle, and water becomes crystal clear
