Aquarium Substrate Gravel (4–6mm, 2kg) – Premium Colored Fish Tank Substrate

Vibrant Customization for Your Aquascape

Transform your underwater landscape into a striking focal point. Whether you want a sleek, modern Jet Black or Crisp White background to make your fish pop, a natural Multi-Color stream bed, or a playful pop of Red, Blue, Green, or Yellow, this substrate allows you to express your unique style.

Optimal Grain Size for a Healthy Ecosystem

Substrate is more than just decoration; it functions as part of your aquarium’s filtration system. The 4–6mm grain size strikes the perfect balance for small to medium-sized aquariums. It is heavy enough to securely anchor live plant roots and plastic ornaments, yet coarse enough to allow water to circulate freely, preventing toxic anaerobic gas pockets from forming due to compacted gravel.

Key Features & Benefits

• Stays Vibrant: High-quality color coating that will not bleed, fade, or discolor, keeping your tank looking pristine over time.

• Fish & Plant Safe: Completely non-toxic formula that won't alter your pH or disturb your delicate freshwater water chemistry.

• Easy to Clean: The gravel's smooth surface allows for effortless maintenance during routine water changes with a standard gravel vacuum.

• Promotes Beneficial Microbes: Provides a vast surface area for essential nitrifying bacteria to colonize, supporting your tank's biological cycle.

Preparation Guidelines

• As with all new aquarium substrates, always thoroughly rinse the gravel in a clean bucket with cold tap water before adding it to your tank.

• Do not use soap or detergents.

• Rinse until the run-off water is clear to remove any safe, micro-fine dust particles caused by transit friction.
