The bead filters are mostly just modified swimming pool sand filters. The
infeed is sent to the bottom, rather than the top, and the out feed is taken
from the top. The beads float, so they catch debris on its way up, and are
readily removed by backwashing. Many have installed hot tub blowers to
assist in cleaning the beads, reducing the amount of water required for a
good cleaning. The bead filters are excellent biofilters with tremendous
surface area, and also good mechanical filters. Look at the web pages for
some of the bead filters to see the internal plumbing.

I acquired a pretty decent sized swimming pool filter with the multi
position valve etc on it. Held about 250 pounds of sand. Cleaned it
all up and its like new, but I already scavenged the internal spray or
filter head out of it for my ponds pump, so I have just a big empty
container. Anything like a filter or what have you that I can utilized
it for with my pond? I know a sand filter wold clog up pretty fast
but any other uses perhaps?
