The AquaClear Foam Insert (A) must be installed in the media basket first. The foam block should totally fill the bottom of the basket and fill the chamber completely to the sides. There should be no space anywhere between sides and foam. Be sure to rinse the insert thoroughly before installation.

The AquaClear Carbon Insert (B) is packaged in a nylon porous pouch over wrapped with a protective plastic dust sleeve. Remove dust sleeve, and rinse the insert to remove any carbon dust particles. To properly install the Carbon Insert, flatten the insert on top of the Foam block already placed in the filter basket.
