Reef Diaper Disposable Filter Socks – Replaceable Elements Starter Kit for Freshwater & Saltwater Aquariums

Effortless maintenance for your aquarium

Never wash another filter sock again. Reef Diaper Disposable Filter Socks replace the traditional 4-inch sock with a low-cost disposable element. The top flange stays reusable, and you simply swap the element for a fresh sock every time, keeping your setup tidy and ready for action.

Why reef diaper stands out

• LOW-COST DISPOSABLE FILTER ELEMENTS: Replace the element and enjoy a clean sock fast. Additional elements sold separately.
• QUICK AND EASY FILTER REPLACEMENT: The design lets you change the element in seconds, reducing downtime and mess.
• DROP-IN REPLACEMENT FOR 4-INCH FILTER SOCKS: Fits standard sumps with a 3.75-inch bore and replaces the old sock.
• PLEATED ELEMENT FOR LARGER FILTER AREA: Over 300 square inches of filtration area, delivering performance similar to a 200 micron felt sock.
• FLANGE SEAL SECURES FILTER AND STOPS BYPASS: Built-in seal prevents waste from bypassing and reduces sock flotation.

Real world use and benefits

The pleated element provides substantial surface area while maintaining strong flow, helping you keep particulate in check without bulky hardware. The reusable top flange reduces recurring costs, and the sealed path helps keep filtration where it should be.

Compatibility and maintenance guidance

Designed for both freshwater and saltwater aquariums, the Reef Diaper offers a compact, straightforward alternative to bulky roller filters. For nutrient management, consider replacing filter elements twice per week to keep your water quality steady.

Starter kit contents
