Premium Ceramic Grey Bio Balls Filter Media (24mm)

Achieve unparalleled water clarity and a highly stable aquatic ecosystem with our Premium Ceramic Grey Bio Balls, available now at www.onyxaqua.com. Engineered for superior biological filtration, these 24mm porous spheres provide the ultimate breeding ground for the beneficial bacteria your aquarium needs to thrive.

Whether you are maintaining a heavily stocked cichlid tank, a delicate planted aquascape, or an outdoor koi pond, this media works silently to break down dangerous ammonia and nitrites into safe nitrates.

Key Features & Benefits

• Innovative Hollow Core: Unlike solid bio balls, these feature a unique hollow interior cavity that maximizes the internal surface area and creates oxygen-depleted zones to support nitrate-consuming anaerobic bacteria.

• Mineral-Infused Matrix: The distinctive grey and brown speckled texture isn't just aesthetic; it contains natural sintered minerals that slowly release essential trace elements to boost fish vitality and enhance coloration.

• Massive Biological Capacity: The ultra-porous, sponge-like ceramic structure allows for rapid bacterial colonization and excellent water flow without clogging.

• Long-Lasting Durability: Kiln-fired at extremely high temperatures, this media is rugged, resists crumbling, and is completely chemically inert (will not alter your pH).

• Customizable Quantities: Available in convenient 250g, 500g, and 1000g (1 kg) packets, allowing you to easily purchase the exact volume required for your specific filter size.

Usage & Maintenance Guide

To ensure your biological filtration operates at peak efficiency, follow these simple preparation steps:

• Preparation: Thoroughly rinse the bio balls in a bucket of dechlorinated water before adding them to your filter to wash away any ceramic dust generated during transit.

• Strategic Placement: Place the bio balls in your filter trays after your mechanical filtration (filter floss or sponges) to prevent the microscopic pores from getting clogged with solid fish waste.

• Safe Cleaning: Never clean your biological media with untreated tap water, as chlorine will destroy the beneficial bacteria. When maintenance is needed, gently swish the balls in old aquarium water during a water change.
