"BET surface area measurements indicate that Matrix contains nearly 10 times the specific
surface area of Substrat Pro, and more than 20 times the specific surface area of MicroMec.
Practically all the specific surface area of both Substrat Pro and MicroMec are in the range of
pore diameters to be biologically useful, while some of the surface area of Matrix is in pores that
are reserved for physical and chemical processes, not biological processes. Estimates from two
different pore geometries indicate that Matrix contains between 4 to 4 . times the biologically
active surface area of Substrat Pro, and between 8 to 9 times the biologically active surface area

of MicroMec."
συμφωνα με αυτο η ελαφροπετρα εχει στο λιτρο 4500 τμ επιφανεια αποικισης το οποιο προκυπτει εφοσον εχει σχεδον 10χ τον χωρο απο το σαμπστρατ το οποιο εχει μολις 450τμ/λτ συγνωμη αλλα εχω πρωσοπικα δεν το πιστευω.http://www.eheim.asia/prod_e_media_bio.html
