Michael, check out this web site
http://www.mvwgs.org/filter.htm . I was
looking through these posts to see if I could find out who posted it to
thank them. I made this filter just Saturday 6/21/03 and it took about 2
hours including the trip to Loews and cost just less than $20. I still have
not figured out who to thank but seeing your inquiry and replying may be my
good deed for the day.
It will take a while until I determine how effective the filter is but I
made sure all the filter pieces fit very snugly together to eliminate the
possibility of accidental bypass or channeling. I have been in the filter
business in the past and this design looks like it should be quite
effective. If anyone else reading this has any long-term experience with
this, please advise your level of satisfaction.
Wait a minute....I just noticed the subject line of "3600gph pump". My pump
is only putting out 500 gph so this may not apply. For $20 bucks, I'd still
try it if I were you and if it got dirty more often than you want you could
make multiple units and put them in series or parallel to extend the
cleaning cycle.
And whomever posted it for me to see - Thank You!

Mike,
My BIL has made a nice prefilter using 2 of the mesh type plant baskets,
round ones, and cutting out a hole in the bottom of each for a piece of
pipe
to go through. The baskets are connected with twist ties open top to open
top. The pipe that goes through has a lot of holes about 1/4 inch
diameter
and a cap on the end. The other end is fitted with an appropriate fitting
for the pump. I modified mine, because the suction was enough to collapse
the baskets once they were covered with debris, by adding bioballs as
internal fill. Works great.

Anybody know how to make an inexpensive pre-filter for a pump? What if I
took a peice of pvc pipe and drilled some holes in it and wrapped foam
around it? I don't want to pay $150 for a filter, especially since I
want my veggie pond to get the nutrients. I just want to keep out things
like mud, acorns etc.
Thanks
Mike
