Precautions for use: ※No washing is required. The soil is prone to crumbling, so when setting it up, use cushioning material and pour water gently, avoiding stirring. Pouring water vigorously will cause cloudiness. ※Even if cloudiness occurs during setup, it will subside within a few hours. Using a filter can quickly remove water cloudiness. Even if the cloudiness is difficult to remove, it will not affect the animals. ※Since it is soil made from 100% natural materials, the particles tend to crumble when strong force is applied. When maintaining, handle it as gently as possible and avoid stirring or pressing it. ※Not suitable for large animals with heavy weight and a tendency to dig up the soil, as the particles crumble easily. ※When using various filter devices, keep them away from the soil to prevent soil from entering the intake. Also, place rocks or driftwood at the outlet to prevent the water flow from directly hitting the soil and stirring it up. ※Not suitable for saltwater, brackish water, or animals that prefer high hardness and alkaline water. Feeding dish not included.
