- Image via Wikipedia
Water filters are important for freshwater aquariums, ponds, and fish tanks. By extending the period before which, the water has to be replaced, these filters help to create appropriate conditions for freshwater fish, plants, etc. The freshwater requirements cannot be created as in the natural habitat; however, you can always adopt certain measures to enable freshwater aquatic life to nourish in the artificial arrangements.
The filters help to remove waste from the water in the aquarium. In the natural fish habitat, there are a lot of plants that help in preserving the natural ecosystem. As the freshwater aquarium is on a smaller scale as compared to the natural habitat of the fish, filters make it necessary to fulfill some of the necessary requirements for a freshwater aquarium.
Water pollutants, also depends on the type of the aquatic life kept in the aquarium. For instance, goldfish produces a lot of waste. There are three main types of filters. They are:
1. Biological
2. Chemical
3. Mechanical
You will get a lot of help if you use all three types of filters. The filters used in the freshwater aquariums these days use all three types of filters.
A short list of the most frequently used biological filters is below:
Sponge filters: In these filters the water passes through a sponge. Bacteria are allowed to grow in these sponges. This type of a filter is a purely biological one. You should never clean or dry the sponge as this can kill the nitrifying bacteria.
Under gravel filters: These filters are also biological ones. These filters take water from the bottom of the freshwater aquarium to the top. These filters pass water from the gravel. You can also look for the reverse under gravel filter. This filter works in the opposite direction to the original under gravel filter. Such a filter brings water through the gravel from the top of the fish tank towards the bottom.
Canister filters: There is a container or basket in these filters that store different filter media. These filters have a certain type of biological balls that helps to grow the bacteria colony. You will not need to remove or clean the filter once a bacteria colony is established in such filters.
