Airmax CrystalClear Filter Media Mesh Bag, 12" x 18"
A heavy-duty mesh bag for holding filter media, activated carbon, or biological media in your pond or filter system. At 12" x 18" (30 cm x 46 cm), it fits inside most pressurized filter chambers, skimmer baskets, and settling chambers. Water passes through the mesh while the bag contains the media, making it straightforward to remove, rinse, or replace media without handling it loose.

How to Use
Fill the bag loosely. Overfilling reduces water flow through the media. Tie or cinch the closure securely. Place in the filter chamber, skimmer basket, or any location where you need contained media with free water flow. To clean media, remove the whole bag, rinse gently in pond water, and return. Never rinse biological media in tap water. Replace the bag when mesh tears or the seam separates.
Suitable for any pond or filter system where loose filter media needs to be contained for easy removal and servicing.
