> 3 dayAs the picture shows, I received 3 packages of the Bio-Carb cartridges with the Zeolite nowhere to be found. I didnt even notice at first until I went to use them later. I started to open the one and it dawned on me. Kind of annoyed because the only reason I bought the set was that it supposedly included both Bio-Carb and Zeolite which isnt easy to find in 1 order. I should probably make my own filter, anyway. As far as quality and effectiveness, theyre totally good.
