Aquarium filter: make and buy filter for aquarium
An aquarium filter does not have to be expensive. It is a filter made for the aquarium. It is intended to keep the aquarium clean. There are different types of aquarium filters, such as inner filters, outer filters, mechanical and biological filters. It is important to clean the filter properly. You can save on costs by buying a second hand filter. Then the price is considerably lower. Read all about it in this article.
Most aquariums have a filter. This filter is used to keep the aquarium clean. An aquarium can quickly get dirty. This can be due to the plants that are in the aquarium, but it can also be due to the faeces of the fish. These end up in the water. If the water is not filtered regularly, this can have negative consequences for the health of the plants and fish. At worst, these could die. A filter is not a substitute for no longer cleaning the aquarium. This too will still have to be done regularly.
Place filter in the aquarium
There are several types of filters. These filters can first be divided into inner filters and outer filters. An internal filter can be placed in the aquarium itself. The disadvantage of this is that there is usually little space in an aquarium. Especially smaller filters can be placed in it. So it is always at the expense of the aquarium space. A filter contains several compartments. The bigger the tank, the bigger the compartments should be. A filter sponge is placed at the entrance. This ensures that coarse parts, such as pebbles, do not end up in the filter. Fish are also stopped by it. A finer sponge is placed behind the filter so that the smaller parts are also filtered out of the water. These filters are usually powered by an electric pump. This can run on batteries or be connected to the mains.
Different types of aquarium filters
There are also so-called external filters. These are filters placed outside the aquarium. A distinction can be made between two types of filters, the siphon and the biologist. The siphon used to be cylindrical, but is now more rectangular. The siphon forms a closed circuit. It is always below the water level of the aquarium. That way the water can run into it. That water passes through different filter layers. The biologist, on the other hand, is a glass container. This is divided into several compartments. The biologist can be placed under or next to the aquarium. The water is pumped into the first compartment of the compartment. All the coarse material is already filtered out there. In the following compartments, smaller debris is filtered out of the water. It is also possible to buy a filter with heating or UV.
Cost and price of aquarium filter
In addition to the distinction between an inner filter and an outer filter, a distinction can also be made between a mechanical filter and a biological filter. A mechanical filter is usually used as a pre-filter. Filter wool and / or a filter sponge are placed. This stops most dirt. This filter must be cleaned regularly. The biological filter follows the mechanical filter. The smaller dirt is removed in it. You can buy a filter at a pet or aquarium store. If it should not cost too much, it is also possible to buy an aquarium filter cheaply second-hand via Marktplaats. That makes a difference in the price. Well-known makers of aquarium filters are Shark, Tetra and Rena. If the filter is broken they can fix it for you too.
