MADE FOR EVERYDAY FILTRATION

Give Your Filter More Ways to Help.

Visible particles and unwanted water tint can call for different types of filter media. This design brings mechanical and chemical filtration together.

🧽 Particle Capture

Outer filter material helps intercept debris carried by the water.

🖤 Carbon Adsorption

Activated carbon helps reduce certain compounds linked to odors and discoloration.

INSIDE THE FILTER CUBE

Two Layers. Complementary Filtration.

The outer filter layer, black honeycomb surface and carbon media serve different roles as water passes through the cube.

01 Outer Filter Cotton

Helps capture larger suspended particles before they continue through the filter.

02 Honeycomb Structure

Multiple channels provide pathways for water movement through the media.

03 Activated Carbon

Supports chemical filtration by adsorbing certain dissolved substances.

PROPER FILTER PLACEMENT

Let the Water Flow Through.

For useful filtration, water needs to pass through the filter media. Position the cube inside a compatible filter compartment with an active water path.

Measure Your Filter

Check the available media-compartment space before choosing a size.

Maintain Water Movement

Avoid blocking the filter's intended flow with oversized media.

Use With Existing Filtration

This cube is supplemental media, not a complete aquarium filter.

EASY FILTER MEDIA CARE

Simple Preparation. Practical Maintenance.

A little preparation before installation, followed by routine checks, helps keep your filtration setup working as intended.

01 · Rinse

Gently rinse new media to remove loose carbon dust, following the product directions.

02 · Position

Place the cube inside a suitable filter compartment with active water movement.

03 · Replace

Inspect the media periodically and replace exhausted activated carbon when needed.

Important: Never use household soap or detergent on aquarium filter media. Activated carbon can also adsorb some aquarium medications, so follow treatment instructions when medicating fish.

Frequently Asked Questions

What does activated carbon help with?

Activated carbon can help adsorb certain dissolved compounds associated with unwanted odors and water discoloration. Results vary depending on the aquarium conditions.

Does this replace my entire filter?

No. This is filter media intended to work within a compatible filtration system. Proper mechanical and biological filtration are still important.

Does it remove ammonia or nitrate?

Activated carbon does not reliably remove ammonia, nitrite or nitrate in normal aquarium use. Appropriate biological filtration, water testing and maintenance are essential.

Can it be used in saltwater tanks?

Saltwater use is included in the supplied product description. Confirm the cube fits your specific filter and intended application.

How often should I replace it?

Replacement frequency depends on water conditions, media loading and filtration use. Monitor performance and follow the manufacturer's recommendations.
