Is this for you?
✔️ Good if:
- You use loose filtration media

Why this media bag?
The Seachem Zip Bag provides a secure and reusable way to contain filtration media while allowing efficient water flow through your filter system.
Its corrosion-resistant zipper replaces traditional drawstring bags, reducing the risk of media escaping into your filtration chamber.
The fine 16 mesh construction is especially useful for smaller filtration products like Purigen, resins, carbon, and biological media.
Common mistakes
- Overfilling the bag → reduces water flow
- Not rinsing media before installation
- Using oversized bags in compact filters
- Forgetting to clean the bag during maintenance
- Using incorrect mesh size for extremely fine powders
Use made simple
- Fill with chosen filtration media
- Zip securely closed
- Place inside filter chamber or sump
- Allow water to pass through media naturally
- Remove, rinse, and reuse during maintenance
Pair with
- Seachem Purigen
- Seachem Matrix
- Activated carbon
- Resin-based media
- Canister or sump filtration systems
Medium-sized zip bags are often the most practical size for hobbyists — large enough for effective media volume but compact enough to fit most canister and internal filters.
