Can someone please post a pic of a bio wheel. I don't know what this is.

I hear people say their bio wheel stopped turning... aren't the things you only 1/2 understand endlessly fascinating? ('cept algebra)

Hi,
As you can see from the previous posts, the water is
pumped into a HOB (Hang On Back [of the aquarium]) filter
where if flows through chambers filled with
charcoal (carbon) and now days, a sponge. The Sponge
removes the particulate matter, and is a combination
of mechanical and biological filtration, while the
carbon is for mechanical and chemical filtration.
Then the water flows through a spray bar whose output
is directed onto the "Biowheel". Its a sort of paddle wheel
and as the water coats the wheel, it rotates dumping the
return water into the tank. Bacterial colonies thrive
on the wheel that alternately is submerged and then
exposed to oxygen (the air), and then resubmerged.
This further purfies the returning water.

Actually, virtually every type of aquarium filter is
modeled after a municipal water treatment plant or
process. Even the fluidized bed filters are commerically
used in water treatment
