High-Density Bionic Cashmere Aquarium Filter Media – Reusable Physical Filtration for Marine & Freshwater Tanks

Achieve professional-grade water clarity with our High-Density Bionic Cashmere Filter Cotton. Designed for serious aquarists, this premium filter media combines the delicate, high-surface-area texture of bionic cashmere with the rugged durability required for long-term aquatic maintenance. Whether you are managing a sensitive reef tank or a high-bioload freshwater community, this media provides the mechanical filtration necessary to trap fine particulates while maintaining optimal flow.

Key Benefits

Advanced Bionic Cashmere Fibers:** The ultra-fine, dense fiber structure mimics natural textures to capture microscopic impurities that standard sponges often miss. Its "hand-tear" design allows for easy customization to fit any filter size or shape.

Superior Permeability & Adsorption:** Engineered for high-efficiency performance, the fiber density is optimized to allow water to penetrate easily while ensuring that waste, uneaten food, and debris are effectively adsorbed.

Eco-Friendly & Glue-Free Construction:** Your livestock’s safety is a priority. This media is manufactured without the use of toxic glues, phenols, or chemical binders, ensuring no odors or harmful substances leach into your water column.

Exceptional Durability and Reusability:** Unlike disposable filter pads that fall apart, this high-density fiber is resistant to clumping and deformation. It is designed to withstand vigorous scrubbing and rinsing, allowing for multiple uses without losing its structural integrity.

Dual-Action Filtration:** While primarily a physical filter, the massive surface area of the cashmere-like fibers provides an excellent environment for beneficial nitrifying bacteria to colonize, aiding in biological filtration.

Key Specs

Material:** High-density bionic cashmere fiber (synthetic).

Weight:** Approximately 250g per unit.

Safety:** Non-toxic, phenol-free, and glue-free.

Compatibility:** Suitable for marine (saltwater) sumps, freshwater tanks, and various filtration systems.

How to Use

1. **Sizing:** Measure your filter compartment (sump, canister, or hang-on-back filter). Hand-tear or cut the cotton to the required dimensions.

2. **Preparation:** Briefly rinse the filter cotton with aquarium water or dechlorinated water to remove any settled dust from transit.

3. **Placement:** Place the cotton in the physical filtration stage of your system. For best results, position it where the water first enters the filter to trap large debris before it reaches your biological media.

4. **Maintenance:** When water flow slows or the media becomes visibly soiled, remove the cotton and scrub or rub it under water to release trapped waste. Reinstall once clean.

Care & Safety

Chemical Avoidance:** Never wash the filter media with soaps, detergents, or bleach, as these will kill beneficial bacteria and may harm your fish.

Storage:** Store unused portions in a dry, cool environment. Keep away from open flames or high-heat sources.

Monitoring:** Regularly inspect the media for heavy clogging to prevent overflow in certain filter designs.

Notes

"High-density fiber. Does not clump easily when washed."
