3. Noting the water level within the disconnected Air Stack, cover the air outlet in the
disconnected Stack with your finger so that all bubbling is limited to the other Stack.
Water level in the disconnected Air Stack will drop. The more it drops, the more
restricted the filter is.
NOTE: If the water drops more than four inches, the filter bed is completely restricted.
If the filter bed is restricted,
but the animals appear normal and water is not hazy,
you have caught the problem in time.A complete tank breakdown is not necessary.You
must, however, change the bottom filter pad to increase the flow through the filter bed.

container which has been filled with water from the tank.Aerate water with white
rigid tube and airstones from tank.

as much dirt as possible in the pad as you roll.

4. Agitate Filter Bed by hand or with a clean
tool.This will open up any blockage.
