Biological and mechanical filtration (great for Koi), suitable for any pond without a waterfall or with a waterfall if the filter is placed at the top so water can gravity feed from the filter. Maximum flow 7000 lph.
- Great value for money.
- Very well made, excellent quality.
- It has many of the features of more expensive filters including a high outlet so half the filter can be buried if needed, provided the cleaning drain outlet is not used.
- Eight separate foams each 39 x 32 x 4cm - 3x Black(Course), 2x Green (medium) 2x Blue (fine) and 1x Grey (Extra fine) for a total of 20m² of surface area.
- High capacity mechanical and biological flow through with multi chamber filters for clear ponds.
There are two types of filtration action in every bio-filter.
- Mechanical filtration.
At the top of each filter is a foam set, these foams physically strain the water removing particles of fish waste and debris from the water.
- Biological filtration
Helpful bacteria to grow on the mat's surface. The bacteria absorbs the pollutants within the pond water and neutralise ammonia and nitrite deposits then recycles the pollutants to nitrate which is a natural plant food.
Ponds can be effected by various factors such as unconsumed fish food, decomposing vegetation and fish waste. If these pollutants are allowed to accumulate, in time they will become harmful to your fish. The use of a biological filter will remove these toxins (nitrate, ammonia) and provide good quality water with the additional benefit of reducing algae growth.
