What order should filter media go?

The first step is to look in the manual and find out which direction the water flows through the filter.
As the water enters the filter media basket, we like to use a coarse sponge pad as mechanical filtration to block the largest chunks of debris and prevent them from entering the rest of the filter media.
If you need to use the ammonia or phosphate media pads, you can place them here since the pads also serve as mechanical filtration.
As a final mechanical filtration layer, you have the option of adding the fine poly pad to catch even smaller particles floating in the water.
The next layer is the biological filtration, so fill the media trays with bio media.
Finally, you can choose to use chemical filtration like activated carbon or Purigen at the very end right before the water leaves the filter and reenters the aquarium.
Not all of these products are necessary, but we do recommend having at least one layer of coarse mechanical filtration and then one layer of biological filtration if you have room.

Mechanical filtration clarifies the water while protecting the other filter media from clogging with debris.
Mechanical filter media include foam pads, synthetic fibers and other mesh type materials.
The idea is the strain out the larger particles first, then trap the small particles.
Chemical Filtration Second
There are many kinds of chemical media including activated carbon pads, bags of carbon-resin blends, and phosphate removers.
Biological Filtration Last
Biological filter media provide a surface for beneficial bacteria to attach and form stable colonies.
No matter which you select, biological filter media should be protected from debris so it does not get dirty and clog up.
The last, and optional, stage is the polishing stage.
You may want to use a final polishing filter to really make the water sparkling clear.
Regardless of the model, there is a logical “order of things” to consider when loading your canister with filter media.

Mechanical filter media should be packed in first so that it receives the flow of raw water.
The general guideline is based on removing ever-decreasing particle sizes while still maintaining the health of beneficial bacteria.
Biological media is usually placed after the mechanical media but before any chemical media.
The coarsest material is placed first.
Chemical media is placed in the final portion of the filter.
You can experiment with combining different media, but maintaining a standard overall order will achieve the best water filtration.
The conditions in your specific tank will dictate which types of filter media you will need, along with the correct order to pack them in.
Placing chemical media before the biological media means that what usually feeds the bacterial colonies will be removed prematurely, before reaching them.
Placing it first in line allows much of the debris to be captured before the water continues on to the other filter media.
