The natural zeolite used in the following study comes from the Hungarian Rátka deposit. It is mainly constituted of clinoptilolite. The particle density of the zeolite is 1.91 g/cm3 and its bulk density is 0.445 g/cm3. Before grinding, the feed material was sieved under 100 µm, with a median particle size of 16.9 µm. Methods

Zeolite powder is made by grinding natural zeolite rock, and the color is light green and white. It can remove 95% of the ammonia nitrogen in the water, purify the water quality and alleviate the phenomenon of water transfer. Adding zeolite powder (150 mesh) to grass carp feed can increase the survival rate of grass carp.
