About this item
- The gravel is CO2 resistant and water neutral, meaning it does not affect the water values and does not dye the water
- Thanks to the rounded grain, it is suitable for keeping bottom fish such as catfish, which continuously search for food
- The optimal amount of gravel can be determined as follows:
- A (cm) x W (cm) x C (cm) / 1000 = number of litres of sera gravel
- International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
