20kg Barley Stone Filter Media - Excellent Water Purification - High Quality Filter Media Continuously Sold in Saitama for 7 Years

Thank you for viewing. This is a high-quality filter media containing Bakuhanseki (medicinal stone). It is in 10mm spherical form.
It excels at stabilizing water quality and biological filtration. It can be used in various filtration devices, including top filters, so please give it a try.
It is manufactured by firing silicate salts at high temperatures.
The countless pores are ideal for bacterial colonization. Being made of glass, it is durable and long-lasting.
Suitable for both freshwater and saltwater aquariums. The amount to use may vary slightly depending on your aquarium's filtration system, so please use an appropriate capacity for your setup.
Before use, lightly rinse the product with water (water only). This product is for aquarium use only; do not use it for other purposes.
The degree of soiling of this product will vary depending on filter performance, the number and size of fish, water quality, etc. Always check the degree of soiling and clean or replace it as needed. (I personally replace it every 3-6 months.)
If left as is, filtration capacity will decrease, potentially leading to the of your fish.
