How do I use P?RA Media Sock
Select media according to your application.

For small drip tray the sock does not need to be tied. Fill with appropriate amount of media, fold the loose end underneath the filled section and bring back and over the top at the opposite end. Even out the media uniformly across the tray.

For wet (sump application) fill with enough material to form a "media sausage" completely across the width of the sump. This ensures optimal and most efficient chemical filtration without water bypass. Tie a knot in the bag at a point that maintains the shape of your "media sausage" and pull relatively tight. The maximum recommended length for a "media sausage" is 26 inches, this leaves enough sock for tying a secure knot.

PURA Filtration Sock can be washed and reused several times.
