Red Sea Filter Media Bag (2-Pack)
The Red Sea Filter Media Bag is the same high-quality drawstring nylon bag Red Sea ships with its Reef Spec Carbon—now sold on its own as a handy 2-pack. The fine, even mesh holds loose filter media securely while letting water flow through, making it ideal for carbon, GFO, phosphate remover, and chemical resins in any freshwater or saltwater system.
