Internal Filters
Air Operated
These are filters that sit in the tank itself. Besides being unsightly, it takes-up precious space in the aquarium. Most of them use a filtering media of sponge with or without activated carbon or just filtering wool.
At the bottom end of filters, are the Air operated type of filters that come in many different shape and sizes. You use filter wool stuffed into a compartment and water is drawn through the filter wool and up the pipe with the air bubbles (uplift). All their functions are similar. Although effective in its own right, its success is limited to the immediate surrounding area and power of the air pump.
As you can guess, the effectiveness is rather limited and depends largely on the air pump itself. These filters are suitable for small aquariums, as most powered types will be too powerful for them.
