| I looked at the filter. It's completely inadequate as far as koi go. Personally I wouldn't use it even on my 2000 liter quarantine tank. The filter is basically a crap-trap. It will filter solids but then acts as a tea-bag forcing water through the trapped junk. As far as biological filtration goes it offers next to nothing. Biological filtration is the most important. It you go with this system you are going to end up with allot of grief and sorrow (not to mention sick fish!)
For what you propose I think the only real option is a bakki shower. with bacteria house media (BHM) It can be pump fed, needs no settlement and you can pump masses of water through it with no trouble... In fact the more the better, The down side? It's not cheap. It looks simple but the media is very dear. But it will get the job done.
Do a search of this site for "bakki shower" and BHM and you will get a lot more info.
