The manufacturer informs:

BioCeraMAX 1200 is a unique element intended for biological water filtration in freshwater and seawater aquaria, paludariums, aqua-terraria and terrarium pools. It is in the form of cylinders made of a porous sintered glass material that ensures a very large filtration surface area (1200m²).

BioCeraMAX is ready for use out-of-the-box and requires no rinsing or other additional action. The contents of the package should be poured into a filter basket or filtration chamber. In order to ensure optimal results, it is recommended to place the BioCeraMAX behind the mechanics element and in front of chemical filtration elements.
