So I was at the Dollar Tree (for the people that don't know it's a store that everything is a $1 or less) yesterday and I came across this...

Cannister Filter: A filter which pushes water through an external canister which contains a filter media such as filter floss, polyester or carbon.

Cannister Filter: A filtration system that consists of an external cannister that contains various mechanical filtration media. Water is pumped out of the tank, forced through the cannister, and then returned to the tank.

If you use a cannister filter, another possibility is to let the CO2 bubble into the filter intake. The CO2 will completely dissolve by the time it exits the filter.

If you have the cash, then your best bet is probably a cannister filter. This is basically a canister with sand in it, through which water is pumped. The fine sand makes a great home for the beneficial bacteria, and holds a huge colony.

Water is mechanically filtered first, hopefully by a good quality cannister filter, or at least by a foam block.

Basic filter types include:
Box filters, Cannister filters (figure 1)
Fluidized bed filters
Power filters (figure 2) ...

The filter floss gets changed in the large cannister filter for the Tiger ray tank every day ...

The best choice for small tanks are power filters, the best choice for medium to large are cannisters or Hang on the back filters and for very large cannister filters are the best.

A common filtration device for this type of system are circulation pumps, cannister filters, algae turf filters, trickle systems, power filters, and many other various designs.
