Product: Aquarium Munster Aqua vital Blue Magic Filter 100g
Synthetic filter medium for use in all commercially available internal and external filters. Because of its ideal structure it traps both coarse as well as fine contaminants. It remains retentive longer, can be rinsed several times and therefore offers a longer service life. aquavital Blue Magic filter floss is also recommended as a spawning substrate and can be used to clean glass without leaving scratches.
