Bio-Plas Micro Filtration Media

Part Number N/A Category




Bio-Plas Micro Filtration Media

Bio-Plas Micro Filtration Media is our smallest media in the range. Due to this media being small in size it lends its self perfectly for use in, Trickle Towers and Fine Filtration in the final chamber.

The Bio-Plas Micro Filtration Media had been designed specifically to create the most effective environment for the nitrification process to take place. This process provides consistent filter performance whilst improving water quality.

Specially designed for fluidized filter beds

When Bio-Plas micro is manufactured its closely monitored on its buoyancy.
Bio-Plas Micro has neutral buoyancy.

Over the years we have noticed when using large amounts of floating filtration media in a single chamber you will find it start to lift its self up. This is due to the filtration media underneath floating. Bio-Plas Micro has been deigned to stop this making for better filtration.
Due to it have neutral buoyancy, it behave “weightless” in the water. This means it takes very little water movement to get the bed tumbling/agitated as a fluidized bed should. We have design the Bio-Plas Micro with the use of one of our aerators from our fantastic Aqua-jet Air Diffuser range in mind.
• Each piece of Bio-Plas Micro is 14mDIA x 9mm
• Each piece of media has 1250mm cubed of surface area
• 1 litre = 300g (approximately)

Bio-Plas Filtration Media Range

How it works
Bio-Plas Filtration Media works by providing a perfect place for a delicate eco-system to develop. Bio-Plus Filtration Media provides a large surface Area for the bacteria involved in the nitrification process to grow. It is this process which removes harmful ammonia and nitrite from the water

The Bio-Plas range contains 6 different types of media;
1. Bio-Plas Micro
2. Bio-Plas Slo-Flo
3. Bio-Plas Volume
4. Bio-Plas Mega-Flo
5. Bio-Plas COMPAC 200
6. Bio-Plas COMPAC 300
All of which has been purposely made for different jobs when it comes to filtration. All media in the Bio-Plas group range in size, buoyancy and colour

Why a plastic filtration media?
Plastic filtration media has many advantages?.
• Plastic filtration media is sterile
• Plastic filtration media will not bio degrade making it a great investment for any filter system due to it lasting a lift time.
• Bio-Plas filtration media is made from 100% recycled plastic

Bio-Plas Filtration Sacks
Here at eco-filtration we know through experience of owning and keeping koi when it comes the time of cleaning your filtration system it can be a time consuming and frustrating process having to remove the filtration media piece by piece. The Filtration Sacks are only available in one size; the reason behind this is once filtration media has been in a functioning filtration system for a while it will start to build up levels of mulma. Depending on how much mulma has build up it can be extremely heavy to life and making it very awkward to clean. The 20 litre sacks make changing and cleaning your filtration system easy.

With each individual 20 litres of filter Bio-Plas filtration media that is purchased we will also supply a free Bio-Plas Filter sack (Please Note: this excludes 100 litres and 1000 liters). Bio-Plas Filtration Sacks will hold up to 20 litres of filtration media.

Litre of Media converted to a volume
20 liters = 20000cm3
100 liters = 100000cm3
1000 liters = 1000000cm3 (1metre cm2)
