The stage 3 7.2 quart container is filled with 24
plastic pot scrubbers. This inexpensive
bio-media is recognized by the hobby
community as an excellent media for cultivating

and non-toxic material.
Biological filtration is accomplished when
aquarium water with excess ammonia, nitrites
or nitrates passes thru the pot scrubbers and
come in contact with the aerobic bacteria. This
bacteria typically takes at least two weeks to
begin growing once the filter is in operation.
