How it works
Bio-Plus Filtration Media works by providing a perfect place for a delicate eco-system to develop. Bio-Plas 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 have 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 the experience of owning and keeping koi that when it comes time to clean 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 built up it can be extremely heavy to life and make it very awkward to clean. The 20-litre sacks make changing and cleaning your filtration system easy.

With each individual 20 liters 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.
