Red Sea Reefer Filter Sock - 225 Micron

The 225 micron Red Sea Reefer Filter Sock is a high quality, reusable aquarium filter bag providing different levels of mechanical filtration. These 10.5"/26cm long filter bags for Red Sea's REEFER and MAX-S aquariums will also fit any standard 4"/10cm filter bag holder.

225 micron felt filter bags are ideal for regular day to day use and enable a longer period between cleaning than with the 100 micron bags.

The 225 micron size will filter out fine particulate matter from the aquarium, and is reusable after cleaning and rinsing in water.
