Betanu Sand is a natural sand with soft light color, usually used for aquascaping in aquariums, suitable for general aquarium substrate or aquatic plant landscaping make-up sand. It is formed by the stream, retaining the original texture and color. The color will be slightly deepened after entering the water, showing the natural landscape of the bottom river style or river flow scenery. With good adaptability and plasticity, it can be matched with different decorations, rocks, and aquatic plants to create more diverse aquascapes, such as biotope aquascape and plant aquascape. The medium particle size of 3-5mm provides some water permeability and reduces water velocity's impact on benthic organisms and plants. Suitable for a wide range of aquarium animals, including benthic organisms and different types and sizes of fish. It can provide root support and space for aquarium plants to grow and take root better. Natural materials containing microorganisms and minerals can help regulate water quality in an aquatic environment and promote the growth of aquatic plants.
