My old filtration 3*330Liter Polyester containers (Static Bed / Moving Bed / Japanese Matting).
After a year i decided to create a small plant filter and changed the water level, after the build my pond contained 30000 Liter.
a year later the pond was expanded again to its later size. at that point i changed the system, in a way so that airlift could be used.
A see through to the 2nd upgrade
2 years ago i decided to create a 2nd filterunit. This filterunit is being build in concrete and a Polyester finish.
the Collector which houses the airlift
A working Crielsieve.
My pond currently consists of 40000 Liter of water, and will be kept clean by (when i’ve done) 2 filters.
3 bottom drains, 1 skimmer, very small plant filter
1st filter: 2 chambers
• Criel sieve
• Moving Bed
• Airlift
2nd filter: 3 chambers (in Progress)
• Criel sieve
• Moving Bed
• Japanese Matting
• Airlift
My pond runs on 2 airlifts and comsumes only 100 watt in total.
At the moment i’ll have 12 koi swimming around.
