I want to build a prefilter for my pump using a bucket and pea gravel. i
don't know how to keep the gravel from going in the pump. Also how to
run the pipe into the bucket, or should I just put the pump under the
gravel?

thanks
Mike

The pump has to be encased in batting or a bag . I put my pmmp in a
bag made of fiberglass window screen to keep gravel and toadples out
of the impeller. Happy water gardening.
