If you want to have your first aquarium or fish tank you must take into account several considerations before diving into the water with this great adventure. Join us and we will help you find the best filter for your aquatic friends.

First you must know the types of Filtration for the filter of your Fish Tank:

In the first place we have “The brute force filtering” which consists of changing water from time to time. It is clear that we can counteract the accumulation of waste and impurities with the partial change of water but we cannot completely eliminate the toxic components that are housed in our fish tank.

In this process of water filtration we have to take into account that it is necessary to have a good filtration system, where we can find different ways to purify the water, such as:

Mechanical Filtration

Each of the particles, large and small, is retained by materials of different thickness, starting with those of greater porosity to trap larger and thicker particles such as food debris, feces, among others. And ending with those of less porosity for the retention of finer particles preventing them from reaching the biological filter.

Biological Filtration

This would be the second phase of the filtration, based on the nitrogen cycle where beneficial bacteria are used to purify the water, because of this, it cannot be bought, and the certain bacteria appear naturally and only take a short time to establish them in the fish tank filter.

It is generally known as aquarium cycling. The bacteria take four to eight weeks to reproduce, colonize and biologically stabilize the aquarium. It is favored thanks to the higher porosity materials.

Avoid cleaning the biological materials with tap water, since the chlorine will end all the aquarium cycling.

Chemical filtration

It is responsible for removing all the compounds and unwanted particles that are in the water and in turn, adding others that are necessary to condition the marine life of the fish tank.

It is quite common to use activated carbon to remove traces of medicines; these chemical materials are always used for a specific purpose, such as:

  • Vary hardness
  • Remove toxins
  • Change the pH
  • End the smells
  • Remove the yellowish color of the water
  • Absorb chlorine

You should also have knowledge of the types of internal filters for fish tanks, which are usually used in small and medium aquariums. Mainly, as support filters.

Fish tank internal filter types:

  • Aquarium sponge filter
  • Corner filter
  • Plate or bottom filter

And in turn, we have external filters for fish tanks, where a siphon is used that carries the water through several filter materials and then returns it clean by the outflow.

Types of external fish tank filters:

  • Waterfall or backpack filter
  • External bottle filter
  • Decantation Filter
  • Dry wet filter
  • Tile filter
  • Algae filter and fluid bed

If you are already the honored manager of a 5 Gallon Tank Filter (fish featured!) it implies you are actually already knowledgeable about the relevance of a really good filter for your little bit of pals.
