Power filters (Hang-On-Back filters) are one of best types of fish tank filters used today. What are the power filters and how does they work to keep your fish tank clean and clear?
What Are Power Fish Tank Filters?
One major advantage of power filters is that it is able to be used along with any filtration system. A power filter generally provides chemical, biological and even mechanical filtration. They run on electricity and comes with an internal motor.
Power filters come in a number of sizes and another determining factor for the choice of filter to select is power consumption. Most power filters are equip with different built-in flow adjusters and multi-directional outlets that can be suited to meet the specific needs of various aquariums.
Usually these fish tank filters hang on the back of the aquarium and suck in water through an inlet tube which is placed inside the aquarium. The water then flows through a series of filtration pads and filter media. The filtration pads act as chemical filters, having contained within them charcoal that also traps debris. The filter media acts as biological filters. After passing through these two filters, the clean water is returned back into the fish tank.
How Do Power Fish Tank Filters Work?
Power fish tank filters are powered by a powerhead which is a piece of equipment located either inside or on top of the power filter. It consists of an electric motor which drive a pump and is sealed in hard plastic. It is this pump that sucks in the water, forces it through the fish tank filters and returns the clean water back into the tank.
The speed and force of the water can be adjusted by regulating the airflow into the filter through adjustable valves. This is a very useful function especially when using power filters in small tanks or when there are small fish present, when having too strong currents into the tanks might be detremental to the fish’s health. Regulating the water flow will also allow its direction to be directed into a specific area of your fish tank.
More Fish Tank Filters Advantages
Another advantage of using a power filter is that it is able to draw water faster than most conventional air pumps. This allows a greater volume of water to be filtered in a shorter period of time. This function is very useful when you have a tank that is very cloudy and need to urgently clear up the water.
While it does need minimal cleaning, there is some maintenance that needs to be done. Generally, what needs regular cleaning every week of fortnight is the filtration pad that will get clogged from the excess food, fish waste and sediments that is sucked into the fish tank filters.
