Effective mechanical and biological filtration is the cornerstone of any successful aquarium, and this large, highly versatile filter pad is designed to trap free-floating debris while providing a massive surface area for beneficial bacteria to colonize.

Because it comes in a generous 90x30 cm sheet, this sponge is the ultimate cost-effective, customizable solution for aquarists running multiple tanks or large custom filtration systems.

Key Features & Benefits

• Cut-to-Fit Customization: The large 90 cm by 30 cm dimensions allow you to easily cut the sponge with standard scissors to perfectly fit any filter tray, sump baffle, canister basket, or hang-on-back (HOB) filter.

• Dual-Action Filtration: The dense synthetic fibers act as a highly effective mechanical trap for uneaten food, fish waste, and plant debris, while the porous structure simultaneously supports biological filtration.

• Durable & Reusable: Unlike flimsy filter floss that must be thrown away weekly, this resilient green sponge can be repeatedly rinsed and reused, saving you money in the long run.

• Universally Safe: Completely non-toxic and chemically inert, making it perfectly safe for freshwater tanks, planted aquascapes, marine reef setups, and outdoor ponds.

Usage & Maintenance Guide

To get the most out of your Xinyou filter sponge and protect your tank's delicate ecosystem, keep these maintenance tips in mind:

Pro Tips for Best Results:

• Preparation: Always rinse the newly cut sponge pad under clean tap water before placing it in your filter to remove any loose manufacturing fibers.

• Placement: Position this sponge as the first or second stage of your filtration setup (mechanical stage) so it catches solid waste before the water reaches your delicate ceramic rings or bio-balls.

• Safe Cleaning: When the sponge restricts water flow, remove it and squeeze it out gently in a bucket of old aquarium water. Never wash it under chlorinated tap water, as this will kill the beneficial bacteria living inside it.
