The Dirt-Free Fish Tank: Freshwater Aquarium Filters
Freshwater aquariums, like any other kind of aquarium, need to be cleaned and freed from all unnecessary particles that have the potential to ruin the aquarium or to harm your aquatic inhabitants inside. Although there is the common manual way of cleaning fish tanks, doing this can often get very tedious, which is why we seek the aid of filters, or more specifically, freshwater aquarium filters.
Filtration methods
The filtration process for all aquariums is usually broken down into three major processes: the biological, chemical and mechanical filtration, each with their own way and own realm of dirt and waste materials to be cleaned.
Biological filtration is the filtration process involving the use of beneficial bacteria to transform several substances in the water. These bacteria literally break down toxic substances commonly found in fish tanks, such as ammonia and nitrites, and transform them into less toxic substances such as nitrates.
Chemical filtration uses the aid of synthetic substances to work out some of the waste material found in water. The reaction of the waste material with the synthetic material allows it to be dissolved, and to be collected easily through the filter. Activated carbon is one of the common materials used for chemical filtration.
Mechanical filtration is a filtration process that involves the use of a filter media to trap solid waste particles in the water. The filter media can be of any material, as long as it can make the waste material stick to it. Regular maintenance of the filter media is required, and it should be replaced periodically.
Filter types
These filters usually involve one or more of the kinds of filtration processes, and it’s entirely up to the hobbyists fish tank specifications whether a certain filter would best suit his or her aquarium or not. Alternatively, you can check out your local hobby stores for freshwater aquarium filters and ask certain experts for advice, but here’s a starting list of filters:
Power filters are the most common in terms of popularity, mainly because they are cheap, usually available at most hobby stores, and relatively efficient. In addition, these kinds of filters are easy to install and use, and you don’t need to suffer much from their maintenance.
Canister filters offer that filtration power that you probably can’t find in other filters. They use a mechanism that forces water in the filter media, achieving greater filtering action than most. You have to be wary though, this type of filters is quite hard to maintain, and at most times quite expensive.
Corner filters were the first kind of filters to be used. It works by the simple action of letting the water flow through the filter and into the filter media, and finally filter the water as the filter media begins forming its own beneficial bacteria colony.
Sponge filters make use of a sponge (believe it or not) inside a tube to hoard beneficial bacteria into them, initiating the biological filtration process. Alternatively, the sponge can also be used as a mechanical filter, as it can also trap certain solid particles into it. Some hobbyists install extra sponges for interchanging purposes.
Fluidized bed filters are a relatively new type of filter that uses the concept of using sand for biological filtration. These sands are installed into tubes and are used as the main filter media, letting beneficial bacteria colonize the sand, and then pumping the water upward, which produces the filtering action.
