MasterLine Zip Bag

MasterLine Zip Bag – High-Quality Reusable Filter Media Bag

The MasterLine Zip Bag is designed for efficient and safe filtration in planted and tropical aquariums. Crafted from extra-fine 250 micron synthetic mesh, it allows unrestricted water flow while securely holding filter media such as MasterLine Purity, activated carbon, peat, or biological rings.

Each bag features a heavy-duty plastic zipper that prevents any leakage of fine particles and ensures quick access during cleaning or media changes. Resistant to chlorine, acids, and standard aquarium chemicals, it remains durable even after multiple uses, making it a sustainable choice for advanced aquarists.
