Why this media bag?
The Seachem Zip Bag provides a secure, reusable solution for holding filtration media while maintaining strong water flow.
Unlike string-tie media bags, the corrosion-resistant zipper prevents accidental opening and reduces the risk of fine media escaping into your filter system.
Its durable mesh construction makes it ideal for chemical, biological, or specialty filtration media in both freshwater and marine systems.
Common mistakes
- Overpacking media → reduces water flow
- Using mesh size incorrectly for ultra-fine powders
- Forgetting to rinse media before installation
- Allowing debris buildup without cleaning
- Using oversized bags in cramped filter chambers
Use made simple
- Fill with desired filtration media
- Zip securely closed
- Place inside canister, sump, or filter chamber
- Allow water to flow through naturally
- Rinse and reuse during maintenance
Pair with
- Seachem Matrix
- Seachem Purigen
- Activated carbon
- Biological filtration media
- Canister and sump filtration systems
Media bags are often overlooked, but they directly affect maintenance efficiency. A quality zip bag makes media changes faster, cleaner, and more reliable over time.
