Geprüfter Lieferant Product Features:
1. Different from conventional sand and gravel, natural materials are selected for heating treatment, and processed into natural irregular particles, without disintegration or pulverization, which can prolong the effective performance.At the same time, it has good permeability and ventilation, which is conducive to the cultivation of nitrifying bacteria and the adsorption of organic substances required by water grass, suitable for the cultivation of water grass.
2. Common water grass can be cultivated, and the water grass with high requirements can be added with CO2, and the effect of liquid fertilizer or base fertilizer is better.
3. The pH value is neutral and the material is stable, so as to ensure that water plants and fish only grow well.
4. Natural material, no dyeing ingredients, will not produce nitrite and nitrate, can be used safely.
Application:
Terracotta, water grass bottom sand, drinking water filter material, good filtering effect, fast nitrifying bacteria culture.

Usage:
1. It only needs to be cleaned once (a small amount of dust will be generated due to friction during the solid transportation of ceramsite). It can be laid for use.
2. After water injection, the water quality will have a slight turbidity, which is a normal condition. Generally, it can be clarified after one or two hours of turbidity.
Precautions:
1. When changing water, it should be noted that water should not directly impact the sand layer.
2. When the upper filter is used, it should be blocked by landscape materials or other materials at the water inlet to prevent the water from directly impacting the bottom sand.
3. When external filtration and internal filtration are used, the filter inlet shall be equipped with appropriate sand control materials to prevent the bottom sand from being sucked into the filter.
