My bottom drain and surface skimmer are gravity fed into the VF and then
pumped from the VF into a bio-filter where it then falls back into the main
pond. The only problem I have, is my make-shift prefilter on my pump gets
clogged and needs to be cleaned about once a week. However, the prefilter
is necessary on the pump intake so that the pump doesn't get clogged which
is a much bigger job cleaning. Any suggestions for a good pump prefilter?


Hi Dan,
I use a slotted planting basket filled with bioballs, put in
the pump and then put all into a meshed laundry basket (with
a slide closure). Then I lower the laundry basket into the
pond. It is easy to raise, just get a pole and hook the
rope closure. I rarely have to clean this filter. Others
have filled the basket with lava rocks, but I found them too
heavy.
