I was considering making a 'silt filter' by using the secondary feed from
the pump to circulate water through a sand filter in a tank, but I have no
idea how effective this would be - I may just bucket the silt out and let it
settle, then return as much water as possible and add the silt to the
compost heap.

If anyone has built an effective filter to remove silt, I would be
interested in the design :-)

Years ago in another life I had a holiday job as a waterworks filter
bed attendant. Passing the water through a tank containing quite
course sand cleared the water.
