Filtration Media

Important aspects to consider when choosing a filter media are: the surface area per unit volume, water distribution and flow characteristics when passing through the media, non-blocking properties, and a low weight per unit volume. For bio-filters the material from which the media is constructed should also have a micro-environment suitable for colonisation by nitrifying bacteria. Many types of plastic media are made from PVC which could be toxic to fish, molluscs, crustaceans and certain bacteria. Our media is made from non-toxic, safe materials.

TMC Bio-Rings

• 1" (210m²/m³) and 1 ¹/₂" (130m²/m³) Bio-Rings have excellent flow through characteristics, making them ideal for trickle filter applications.

• Designed to give a large, accessible surface area which is easily contacted by the water (usually falling downwards) and gas, whilst avoiding clogging.

• Made from blue polypropylene.

• Positively buoyant.

Oolitic Sand & Gravel

• Available in five different particle sizes, including our specially graded uniform particle size sand for fluidised sand bed filters.

• Ideal as both a mechanical and a high surface area biological filter media.

• Surface area > 10,000m²/m³.

• Natural Aragonite.

AFM Media

• Advanced Filtration Media.

• Available in three different particle sizes depending on the application's requirements.

• AFM back-flushes with much less water than traditional sand.

• AFM media's smooth surface makes it very difficult for bacteria to colonise.

(Normal filter sand has a rough microscopic surface, which is the perfect environment to attract bacteria. Sand is also prone to becoming coated in fats, lipids and other contaminants. Build up of the fats and bacteria can cause sand bed packing and channeling. When this occurs, filtration efficiency effectively drops to zero).

Bio-Glass

• Made from natural silicate.

• Pore diameter ranges from 60 to 300 microns.

• No toxins - harmless to aquatic species.

• Provides a very large surface area compared to ordinary bio-rings.

• Suitable for both aerobic nitrifying bacteria and anaerobic denitrifying bacteria.

• Suitable for freshwater and saltwater applications.

We strongly recommend that bio-glass is used together with mechanical filtration.

HSA Media

• A high surface area media, ideally suited for submerged/moving filters.

• Elements are 13mm in diameter.

• Made from virgin HDPE (polyethylene).

• Positively buoyant.

• Surface area 800m2/m3.

Curler Advanced Media

• Improved cleaning.

• Very high nitrification capacity.

• Cost effective with long life-span.

• Proven technology.

• Large effective surface area 800m2/m3.

HR Carbon

HR Carbon is a highly retentive carbon which is the result of several years development and testing in freshwater and marine aquariums. It is made from carefully selected grades of bituminous coal, ensuring that a consistent quality is maintained.

• Recommended for the removal of organics and other toxic substances which gradually build up in marine and freshwater aquariums.

• Removes phenols and other organic compounds.

• Unlike many cheaper carbons it does not add any phosphates.

• Creates crystal clear water allowing better light penetration for maximum plant and coral growth.

Use approximately 1g/litre of system water. Change approximately every three weeks depending on loading. Before use, rinse carbon thoroughly in a fine net to remove any dust created during transportation.

Sulphur Media

Sulphur media is formed from pure sulphur and is used to encourage the growth of denitrifying bacteria.

For use in nitrate filters.

Filter Media Bags

These durable polyester filter bags are excellent for retaining carbon, zeolite and other chemical media.

They are perfect for placing in sumps, trickle filters, bag filters and pond filters, etc.

Bags feature drawstring closing tops and are available in 250 micron mesh size.
