 Fish Tank Filters & Aquarium Filters
Why have an aquarium filter? The function of an aquarium filter is to clean the fishes' environment. Chemical toxins and tiny particles are separated from the aquarium water. The removal of such agents allows water quality to remain within an acceptable level for your fish. Aquarium filtration is essential in most aquariums. With good filtration the inhabitants will generally grow larger or more fish can be housed.Aquarium Filter Capacity The size of the filter system required will be determined by your individual situation. When choosing a filter consider:- The size of the aquarium
- Type & size of inhabitants
- How often you want to clean the filter.
- The amount and type of fish food you put into the system
Which filter should I choose for my fish tank? Most manufacturers model sizes are based on the LPH (litres per hour) they will process. As a general rule of thumb you need to aim for water turnover approx. every 2 hours for most aquarium set ups. If in doubt, it is always safer to go to the next size up. For large aquariums it is better to have 2 smaller units (one placed at either end of aquarium) as this will give better circulation. There is also the choice between internal and external filtration. For most average set-ups in small to medium size aquariums, internal filters are quite sufficient and many on the market these days have the facility to house a selection of media to increase efficiency. For heavily stocked, large aquariums or set-ups that house particularly messy fish or specialist marine set-ups it will generally be more efficient and easier maintenance if 1 or 2 (depending on aquarium size) external filters are used which can normally hold a greater range and amount of filter media. There are also units available that incorporate a UVC for killing off unwanted algae etc within the system.
