Base Case Assembly

Most filters fall into three categories, namely mechanical, chemical or bacteriological filtration base. The aquarium supply scene is so diversified and a multitude of products available that it becomes a little confusing to make a quick choice without studying the competitive data. You must carefully prepare your "brief" and specify all your requirements before deciding on the type of filtration to be used.

What & Why of Aquarium Filtration Units

Fish and organisms cause pollution in the form of waste and if not removed would cause toxin development and consequent illness of the fish. The aquarium filtration units consolidate this waste and purify the water that recycles back into the fish tank. The assembly of a filter relies on filtration media that serves the purpose of removing chemicals, particles, and bacteria. Commonly filters are available as packaged units with mechanical and bacteriological media. Chemical filtration can be added to this. Nitrogen residues in the form of ammonia causes distress to fish and the bacteriological filtration unit remove this component very successfully.

Short description of Aquarium Filtration Units

There are four basic types that you can install in case you are assembling your own aquarium. These are:

* Internal Power type

* External Power type

* Powered filters

* Internal box type filters

Let us compare the features of each filter assembly.

1. Internal Power driven filters are in two parts. The main cylinder contains a bio foam compound and is attached under the submersible pump that drives the filter. This is a mechanical filtration system and is most common in aquarium filter units integrated with fish tanks. The filter unit first mechanically filters the water, removing sludge and solid waste etc and then the bio-filter cleans the water of all biological impurities. It is also possible to have an option of chemical filtration, if that is desired or necessary. As this is the most common type of filter almost all manufacturers can supply a suitably sized filtration system to the aquarium owner.

2. External filter unit are also widely available and give superior duty in comparison with the internal aquarium filtration units. Since these are not integrated into the fish tank the capacity and duty may be of a higher quality and obviously cost compared to the previous internal type. The control is better and one can incorporate additional accessories that enhance the filtration of the water for your aquarium.

3. Air driven under gravel filters was earlier used by aquarium owners when the power driven versions were still in its nascent stage. This is a kind of biological filter where the water is purified and kept in constant motion through the gravel bed and the aerobic bacteria produced breaks down the waste into less toxic products, thereby rendering a pseudo-filtration action. The assembly is electrically driven or can be attached also to a power pump. Easily available and of a lower cost, the under gravel type of aquarium filtration units offer an easy solution to keeping your aquarium clean and healthy.

4. Finally, air box filters driven by internal air are compact and fit alongside the aquarium fish tanks. They are made of plastics and contain suitable filtration media. The air box filters are no longer used in professional or commercial units where the previous three types are more popular. They can provide low cost easy installable aquarium filtration units that a newbie or small fish tank owners can easily use.
