The Red Sea Felt Fine 225 Micron Polish Filter Bag is a high-quality mechanical filtration solution designed to remove fine particulate matter from your saltwater aquarium. This filter sock effectively traps free-floating debris, uneaten food, and organic waste before they can break down and negatively impact your water quality. Utilizing this bag in your sump results in crystal clear, polished water, enhancing the visual appeal of your reef and promoting a healthier environment for your corals and fish.

This filter bag is constructed from durable felt material and features a 225-micron rating, which is ideal for fine polishing and removing smaller particles that coarser filters might miss. Measuring 10.5 inches in length with a 4-inch diameter opening, it is designed to fit most standard filter sock holders, including those found in Red Sea's popular REEFER and MAX aquarium systems. The robust construction ensures it can be cleaned and reused multiple times, offering an economical and effective way to maintain superior water clarity.

This product is perfect for any saltwater hobbyist, from beginner to advanced, who prioritizes pristine water conditions. It is especially beneficial for use after tank maintenance, aquascaping, or during periods of heavy feeding to quickly clear up cloudy water. By incorporating the Red Sea Polish Filter Bag into your regular filtration routine, you can consistently maintain a clean and healthy aquatic environment, allowing your reef inhabitants to thrive.
