Koi pond box filter - New setup. I have now added 30 - 40kg of alphagrog and a 400 micron filter sock to collect the muck. I have also re arranged the Brushes. The water looks dirty because i have stirred the bottom of the pond up a lot to get all of the muck out of the pond and into the filter sock.
