What ever u do my mate for the size of pond ur planning u need ur filter size to be at least 30%of pond volume.Do not skimp on this side of things (price wise) or u will find when ur pond is up and running u will start having water problems as ur filter if too small will not cope with the stocking levels.(more fish more demand on filtration)Good luck envy u as i build koi ponds for living
