tunze 930 zeolite

I note that Tunze is also selling zeolite.

How does this work? the zeolite looks the same as zeovit rocks.

Zeolite is a naturaly occuring mineral called Clinoptile, it has a long history in the hobby, Kent Denitrate is also a zeolite. It works very well, on my 75 I packed a 2217 Eheim with 2L of Ehfimech, a blue foam pad and 2.1 liter of Zeolite 930 and when added to the tank Nitrate was at 100ppm (cured live rock in tank), after a few weeks it was down to 2 ppm, now 3 months later it is steady at 1-2 ppm and I feed regularly.
