This internal filter for fish tanks is fully submersible filters that are placed inside your fish tank. Unlike external filters that need to be kept in cabinets or hang on the back of your fish tank, internal filters are placed right inside your aquarium saving you lots of space in your room and preventing unnecessary clutter.
Features of internal filters
Internal filters are
- very easy to set up,
- small and relatively quiet,
- provide excellent filtration while being easy on your wallet.
Fully submersible (internal) filters are perfect because they also double as water pumps; especially if you have an area in your aquarium where water flow needs to be increased. They are effective if your tank carries a high bioload and is in need of supplemental filtering. With the use of special BIO – BALL filtration systems, the internal filters help clean and clarify you tank.
The filter can be affixed with suction cups to the tank walls, or placed on the ground of the tank. Most people place it in a corner of the tank, and most internal filters come with suction cups, so you may not have to purchase them separately
