Simply Koi and More Koi

has anybody converted these into a filter system. i have 3 of them on there way to me and was thinking of dividing each one into two then making a 6bay filter from them. I would appretiate if anybody has any photos (if anybody has done this) it would be great to be able to use them

Did this one some time ago. Still running it on my fry tanks.
