Product Details

✓【Multiple Scenery Usage】 Ideal for Amazonian, West African, or tropical Asian biotope aquariums. It can be used with dense green aquatic plants such as Amazonian sword leaf, java moss, water fern, dark stones, and woody elements such as roots and branches to form a natural and wild landscape. You can also amplify dark features to create a deep sea style with a mysterious atmosphere or warm tones to create a peaceful and romantic twilight style.

✓【Improving Ornamental Appeal】 Red and black mixed tones bring depth and warmth. The color deepens after entering the water and appears deeper, increasing the sense of space inside the aquarium and making it look more spacious. Beneficial to accentuate the color and form of the aquascapeing, when combined with bright greenery, this sand is perfect for creating a high-contrast water feature.

✓【Outstanding Lighting Effect】 Combining different light colors will present a completely different effect. Red and black are clearly visible in white light, with a more realistic and distinctive effect. Under yellow light, highlight the red part, creating a warm tone atmosphere. Under blue light, highlight the black part to create a deep sea or moonlight effect.

✓【Excellent Ecological Performance】 The mixed size of 0.4-0.9mm can provide an excellent filtration effect, which helps to maintain clean water and keep oxygen flowing in the water while providing a suitable environment for aquatic plants to grow. And it contains natural organic substances, which help plant growth.

✓【Natural Material】 Taken from the natural riverbed without pollution, retaining its actual original state. Without chemical processing, safe and friendly to aquatic organisms. After layers of screening and high-pressure cleaning, the particles are uniform, with a 0.4-0.9mm diameter. 2L per bag, about 9 lbs.
