I began getting the unassembled tetra whisper bio bags filled with carbon activated, charcoal , which i like because the bag itself ,can be used several times once' d rinsed in the water change , water, keeping the good bacteria , Only a few times then get a new bio bag out, which there is plenty of in this kit, and CHEAP. , then the charcoal keeps impurities, out of the tank and water clear. Because they are so inexpensive taking only a few minutes to fill , opposed to a one time pre-assembled. . I wouldn't buy it any other way again because there is always plenty on hand. .

Black beads " charcoal " Should be larger to absorb the bad products in the tank . I feel it's better to use a kitchen sponge. Is better.

The Tetra Bio Bags are bags that you fill yourself using the charcoal provided. However, because the bags are fillable by the aquatist, you have the option of adding extra charcoal or Zeolite if you like.
