Hi,
The Ultra sieve 3 will allow 2 x 4" Gravity inputs and 1 x 2" outlet with a Max flow of 4400 GPH, so it has been done before.
As mentioned have a trip out to Richdon Koi they will help with your planning and suggest the right gear to do the job right first time.
They have their own brand of bead filters and pumps to match which have very good reviews.

Dave.

Richdon Koi are only open at weekends, bit of a pain but they like to rest the Koi in the Fish House.
I am sure you will be impressed with the setup, just mention that you have have spoken to me, and they will double the price of everything LOL.
