BjornD's Pond

[bjornd]

Here are some pictures of my pond over the years when i rectangular pond which contained 24000 Liters of water. This pond was filtered by a small but very efficient DIY 3-chamber filter (Static Bed / Moving Bed / Japanese Matting).














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.

How many liters do you move per hour?

Hi frank,

I don't know exactly. i think my airlift does about 10000 L/hour.
I'm planning to place a drumfilter, so all of my bottomdrains go over the drum. then the crielsieve will be removed.
and all of my airlifts going to work

[Frank]

Ok. Why you are going to replace the crielsieve?

i'm planning to place a drumfilter which give me the possibility to increase my flow, reduces bends at the inlet. and keep the water clearer.

at the moment i'm building my quarantaine container, with drumfilter which feeds an Eric filter with about 2000l/h and a big airlift. after this i'm gonna create the plans to change the pond filtration.
