Seachem Filter & Sock 100 Micron Welded 4" x 12"
Seachem Filter Sock 100 Micron Welded 4" x 12" provides fine mechanical filtration for aquarium sump systems by capturing small particles, detritus, uneaten food, and suspended debris before they move through the rest of the filtration system. This helps improve water clarity and keeps sump areas cleaner in freshwater and marine aquariums.
With a 100 micron filtration rating, this filter sock is ideal for polishing aquarium water and removing fine particles that can make water look cloudy. The welded ring design helps provide a secure fit in compatible standard 4-inch filter sock holders.

When to Use a 100 Micron Filter Sock
A 100 micron filter sock is useful when you want finer mechanical filtration and clearer water. It is especially helpful after water changes, substrate disturbance, tank cleaning, feeding, or any time fine particles are suspended in the aquarium.
Because 100 micron socks capture very fine debris, they can clog faster than larger micron socks. Check and clean them often to maintain proper water flow through the sump.
Directions for Use
- Place the filter sock into a compatible 4-inch filter sock holder.
- Direct aquarium water flow through the sock.
- Monitor water flow and debris buildup regularly.
- Remove and rinse or wash the sock when it becomes dirty or clogged.
- Allow the sock to dry fully before reuse when possible.
Maintenance Tips
- Clean every 2–4 days in heavily stocked or high-debris systems.
- Some aquariums may need cleaning more or less often depending on feeding, livestock, and flow rate.
- Avoid using soaps, detergents, or household cleaners.
- Keep extra filter socks on hand so one can be in use while another is being cleaned.
- Replace the sock if it becomes damaged, stretched, or difficult to clean.
Why Use a Welded Filter Sock?
Filter socks are a simple and effective way to improve mechanical filtration in sump-based aquariums. The welded ring helps the sock sit securely in compatible holders, while the 100 micron mesh captures fine debris before it breaks down in the system.
Regular use and cleaning can help improve water clarity, reduce debris buildup in the sump, and support easier long-term aquarium maintenance.
Frequently Asked Questions
What does 100 micron filtration mean?
The micron rating refers to the size of particles the sock can trap. A 100 micron filter sock captures fine debris and suspended particles that can cloud aquarium water.
How often should I clean this filter sock?
Cleaning is typically needed every few days depending on aquarium load, feeding, flow rate, and debris buildup. Heavily stocked tanks may need more frequent cleaning.
Is the Seachem Filter Sock reusable?
Yes. It can be rinsed or washed thoroughly and reused. Do not use soaps or household detergents.
Can this be used in freshwater aquariums?
Yes. This filter sock can be used in freshwater or marine sump filtration systems.
What size holder does this fit?
This welded filter sock is designed for compatible standard 4-inch filter sock holders.
Is 100 micron better than 200 micron?
A 100 micron sock traps finer particles and polishes water more closely, but it may clog faster. A 200 micron sock allows more flow and usually needs less frequent cleaning.
