Patented Hollow Bio Quartz Balls 100g (dual function - ammonia & nitrate removal)

Take your aquarium’s filtration system to the next level with Hollow Core Bio Quartz Balls – an advanced filter media engineered to support both nitrification and denitrification.

Unlike standard solid balls that only host aerobic bacteria on the surface, these specially designed hollow-core structures provide internal zones with lower oxygen levels, allowing anaerobic bacteria to thrive alongside their aerobic counterparts.

This innovative dual-environment structure enables a complete nitrogen cycle inside your filtration system: toxic ammonia and nitrite are broken down on the outer surface by aerobic bacteria, while nitrate – the end product – is reduced inside the core by anaerobic bacteria, helping to minimise nitrate buildup and support a more stable, low-maintenance ecosystem.

Thanks to its innovative patent-hollow design, it provides deep anaerobic zones for denitrification.

It also features a massive surface area structure of 21,260 sq ft per gallon, facilitating extensive colonisation by beneficial bacteria.

(Filter bag is not included. We recommend getting filter bag for this which is available in our other listing at bottom of this page)
