@ycnibrc So you said you aren’t running zeo rock anymore, does that mean you don’t have a zeo reactor online? If you are running this without a zeo reactor I’m very interested in starting this. I did order the kz amino acid concentrate, coral vitalizer, coral snow, and trace element 4 pack for non zeo systems. I wanted to try the brand out. It seems now that I could run the bacteria’s too without a zeo reactor though? Any thoughts are appreciated. Tank is a 90 gal, year and a half old tank on triton/Red Sea hybrid method with tropic marin pro salt.
