Continuum Bact-Rox Extra Large Bio Filter Media 1L - CLEARANCE

Continuum Bact-Rox Extra Large Biological Filter Media 1L

Give beneficial bacteria a porous home in your aquarium filter. Continuum Aquatics Bact-Rox Extra Large is biological filtration media for freshwater and marine aquariums, ponds and other aquatic systems. This listing is for 1 litre of the Extra Large media.

Biological filtration support

The porous structure provides internal surface area for bacterial colonisation, supporting nitrification and providing anaerobic or anoxic areas that can foster denitrification. It can be used as the primary biological filter medium. It is a surface for beneficial bacteria to colonise, rather than an instant chemical ammonia or nitrate remover.

How much do I need?

Continuum recommends a minimum of 100mL of Bact-Rox per 40 litres of aquarium water, with more media where the biological load requires it. At this minimum rate, a 1-litre pack provides media for approximately 400 litres. This is a starting quantity, not a guaranteed filtration capacity for every aquarium.

Preparation and placement

• Rinse thoroughly in aquarium water or purified tap water before use.
• The rinsed media can be placed directly into your filter.
• Use filter floss, a sponge or another mechanical pre-filter before the media to help prevent debris from fouling it.
• For optional pre-seeding, Continuum recommends submerging the media in aquarium water in a plastic bucket with the recommended aquarium dose of its BacterClean or BacterGen product for 24 hours, gently agitating occasionally, before placing it in the filter.

Check filter fit before ordering

Extra Large identifies the media size, not the pack volume. Confirm that the pieces will fit your filter's media compartment before ordering. Individual piece dimensions have not been verified for this listing, so suitability for a particular internal, hang-on or canister filter is not guaranteed.
