IceCap 4in Filter Sock with Plastic Ring (200 Micron)
Maintaining pristine water clarity and preventing organic detritus build-up in marine and freshwater sumps requires reliable first-stage mechanical filtration. The IceCap 4in Filter Sock with Plastic Ring (SKU: IC-FB400P) is an official OEM 200-micron felt filter sock designed to fit standard 4-inch sump filter sock holders. Positioned directly under drain line downspouts, it intercepts free-floating debris, fish waste, and uneaten food before water passes to secondary filtration chambers.
Constructed from dense 200-micron needle-punched felt, this filter sock provides high particulate trapping capacity without clogging as rapidly as finer micron ratings. The integrated rigid plastic collar seats flush into standard sump mounting plates, preventing unfiltered bypass around the edges while making maintenance swapping quick and clean.
Ideal Application Scenarios
Standard Sump Drain Filtration: Direct drop-in mechanical polishing for sumps with 4-inch filter sock receiver plates.
Particulate Trapping: Excellent for capturing suspended debris after glass cleaning, aquascaping, or heavy feeding.

Installation & Set-Up Guidelines:
Turn off or pause the main return pumps to reduce drain line flow.
Carefully pull the dirty filter sock out of the 4-inch sump receiver bracket using the integrated plastic handle.
Rinse the new IC-FB400P filter sock with fresh reverse osmosis (RO) or tap water to remove manufacturing dust.
Drop the plastic ring firmly into the 4-inch sump holder opening until seated flush.
Restore return pump flow and verify water flows through the center of the sock without spilling over the ring.
Pro Tips:
- Rotate Multiple Socks for Easy Washing. Keep a spare set of filter socks on hand. When one set becomes clogged, swap in clean dry socks immediately and soak dirty felt socks in a bucket of water with a splash of unscented household bleach to break down trapped organic waste.
- Dechlorinate and Dry Completely. After washing bleached felt filter socks, rinse them thoroughly with fresh water and soak in water treated with double-dose dechlorinator (such as Seachem Prime). Allow the socks to dry completely before placing them back into service.
