ADA Bio Cube

ADA Bio Cube – Biological Filter Media for Aquarium Canister Filters

ADA Bio Cube is a biological filtration media designed for external aquarium filters. Its highly open polyurethane structure provides a large surface area for beneficial microorganisms while maintaining excellent water flow through the filter.

The media is designed for long-term use and helps create a stable biological filtration environment in freshwater and planted aquariums.

Available Variants

• ADA Bio Cube – Black
• ADA Bio Cube – Blue

Your current Aqua Zones product is configured as a variable product with Black and Blue options.

How ADA Bio Cube Works

Bio Cube acts as a biological filtration medium by providing a large internal and external surface for beneficial bacteria to colonize.

These bacteria help process dissolved organic waste and nitrogenous compounds generated inside the aquarium, supporting more stable water quality.

High Water Flow and Open Structure

The porous cube structure allows aquarium water to pass efficiently through the media while exposing a large surface area to beneficial microorganisms.

Unlike dense filter materials that can clog quickly, Bio Cube is designed to maintain good circulation through the filter when correctly maintained.

Durable Polyurethane Filter Media

ADA Bio Cube is made from a durable polyurethane-based material that does not easily deteriorate during normal aquarium use.

The structure is water-stable and suitable for prolonged use as biological filter media.

Ideal for External Canister Filters

ADA Bio Cube is particularly suitable for external canister filters where multiple filtration layers are used.

It can be combined with mechanical, adsorption and other biological media to create a balanced filter setup.

Recommended ADA Filter Media Combination

For a more complete filtration system, Bio Cube can be used alongside other ADA filter media such as:

• ADA Bio Rio – porous biological filtration media
• ADA Bamboo Charcoal – adsorption media that can continue supporting biological filtration

This combination allows different filter media to handle mechanical, chemical and biological filtration roles within the same canister filter.

Where to Position Bio Cube in the Filter

ADA Bio Cube is generally used as part of the biological filtration section of the filter.

It should be placed where water has already passed through the main mechanical filtration stage, helping reduce excessive debris accumulation on the biological media.

The exact media order depends on the filter design and water-flow direction.

How to Use ADA Bio Cube

1. Rinse the media gently before first use.
2. Place Bio Cube inside a suitable filter basket or compartment.
3. Ensure good water flow through the media.
4. Combine with mechanical filtration and other media as required.
5. When cleaning, rinse gently using aquarium water rather than untreated tap water where possible.
6. Avoid aggressively cleaning all established biological media at the same time.

Why Biological Filtration Matters

Biological filtration is one of the most important functions of an aquarium filter.

Beneficial bacteria colonizing Bio Cube help process waste products produced by fish, microorganisms and decomposing organic matter, contributing to a more stable aquarium environment.

Bio Cube vs ADA Bio Rio

Both Bio Cube and ADA Bio Rio are designed primarily for biological filtration, but they use different physical structures.

• Bio Cube uses an open polyurethane cube structure with excellent water flow.
• Bio Rio uses highly porous natural-style media that offers substantial bacterial colonization surface.

They can be used independently or together depending on filter capacity and the filtration strategy of the aquarium.

Bio Cube vs Bamboo Charcoal

ADA Bamboo Charcoal initially provides adsorption filtration and can later continue to serve as biological media.

Bio Cube, in contrast, is intended primarily as a dedicated biological filter medium from the beginning.

Who Should Use ADA Bio Cube?

• Planted aquarium keepers
• Nature Aquarium enthusiasts
• Aquascapers using external canister filters
• Aquarists wanting high-flow biological filtration media
• Users building multi-stage filtration systems
