The Dr. Tim's Standard Mesh Bag is a versatile and reusable solution for containing your favorite filter media within your saltwater aquarium's filtration system. This bag is designed to securely hold various types of loose media, such as activated carbon or GFO, preventing them from scattering throughout your sump or tank while allowing for optimal water flow through the contents. Its simple design makes adding, removing, and replacing media a quick and clean process, streamlining your aquarium maintenance routine.

Constructed from durable nylon, this 6 by 8 inch bag is built to withstand the harsh saltwater environment without degrading. It features a 1000 micron mesh, which is ideal for larger particulate media, ensuring maximum water contact and efficiency without the risk of clogging. A key feature is the non-metallic, plastic zipper that is completely reef-safe and will not rust, corrode, or leach any harmful substances into your aquarium water, ensuring the long-term health of your inhabitants.

This filter bag is an excellent choice for any aquarist who utilizes granular filter media in their sump, canister filter, or hang-on-back filtration system. Its larger mesh size is particularly well-suited for hobbyists using pelletized carbon, GFO, bio-pellets, or other coarse media that require high flow. The durable and reusable nature of the bag makes it a cost-effective and essential tool for maintaining pristine water quality in any reef or saltwater aquarium.
