Red Sea Reefer 225 Micron Thin Mesh Filter Bag 100mm/260mm

Description

Red Sea Reefer 225 Micron Thin Mesh Filter Bag 100mm/260mm — Easy-clean monofilament filter sock for new setups and heavy maintenance

The sock that comes in a REEFER box is this one, and there is a reason Red Sea chose it. Red Sea Reefer 225 Micron Thin Mesh Filter Bag 100mm/260mm (SKU: RED519a) is Red Sea’s 225 micron thin-mesh filter bag, a monofilament sock 26 cm long for standard 10 cm holders, the bag supplied with REEFER and MAX-S systems. Red Sea’s case for it is practical: the monofilament construction makes it very easy to clean, which suits new setups and the days after heavy maintenance, when a great deal of particulate matter is in the water and a sock may need rinsing twice in a day.

Because mesh catches debris on its surface rather than in a felt wall, it rinses clear under a tap in seconds and dries fast, and the open weave keeps flow up during the cloudy first weeks of a tank or after a sand stir or rock scrub. Red Sea also notes the bag can hold other mechanical or chemical media, so it doubles as a carbon or phosphate-media bag in a sock holder. For settled day-to-day running the 225 micron felt (RED519) holds more between changes, so many keepers keep one of each: mesh for messy days, felt for quiet ones. Reusable, sold singly.

Usage & Application

When to Use

• New aquariums: Clearing dust and particulates in the first weeks of a REEFER or MAX-S.
• After heavy maintenance: Sand stirring, rock cleaning and rescapes that cloud the water.
• Quick-rinse routines: Keepers who would rather rinse a sock daily under the tap than wash felt weekly.
• Media bag duty: Holding carbon or other loose media in the sock holder without a reactor.

Installation Guide

• Rinse and fit: Rinse in tank water, seat the ring in the 10 cm holder with the drain feeding into the bag.
• Watch the level: Water rising in the bag means it is loaded; lift it out and rinse.
• Rinse under the tap: Monofilament mesh clears with a quick rinse, no detergent, and dries fast.
• Swap to felt when settled: Move to the 225 micron felt once the water runs clear day to day.
