Hi all,
I've been reading a bit about a
"Fluid Bed Filter" with coral sand in it.
The sand is supposed to swirl around inside
the tube. Apparently you can make a
pressurized vessel type as well so that you
can still pump water to a waterfall.
Would one of these work alone or do you
have to use them in conjunction with another
filter type? And UV light filters? I'm new
to the fish pond arena, (500 gal), and it seems
to be turning into a lot more hassel than it
needs to be. I'm pretty sure I'm doing it not
quite right.
Any ideas or help here? Information, websites,
etc.

Thanks,
Mark
