Types of Aquarium Filters

Not all fish tank filters are the same. They vary by the working flows, the designs, the materials, and so on. However, we can mostly divide aquarium filters into two categories, as follows:

  • Internal power filters: This type of filter is common for small tanks. In which, a water pump is sitting on a small canister with a small sponge to trap debris and break down waste.
  • External power filters: This conventional filter is crafted with a sealed canister, an outlet pipe, and another inlet pipe. Thus, the whole construction is quite bulky but powerful.

Must-know Aquarium Filter Buying Factors

The filtration process

The best quietest aquarium filter, in particular, and the tank filter – in general, should feature at least three filtrations to ensure a healthy water environment.

  • Mechanical filters: They are the very first filters found in most tanks to sort out solids, small particles, and dust. Thus, mechanical filters prevent build-up and relieve the work of other filters significantly.
  • Chemical filters: As the name suggests, chemical filters come with media that are effective to filter out the harmful chemicals to maintain the water quality. Two common chemical filtration processes are ozone oxidation and protein foam skimming.
  • Biological filters: These parts help increase the natural bio-load in the tank by facilitating the colonization of bacteria, which are beneficial during the nitrogen cycle.

 

The water-flow rate

The water flow rate, which indicates the gallons of water passing through per hour, usually goes hand in hand with the efficiency of the filter.

The higher the rate is, the faster the filter can purify your tank. However, it also means the more powerful and noisier motors.

Thus, if you look for the quietest aquarium filter system, consider this factor.

Do you need such a high water flow rate? Or, how to reduce the noise?

The size and construction

Plus, take the dimension and the type of aquatic filters into account.

For example, you prefer the quietest internal aquarium filter, make sure it is compact enough to not take up more room in the tank, while it is still capable of filtering and ease of installation/setting up.

Warranty and brands

Obviously, you do not have to spend all of your pockets for an aquarium filter. Yet, you should not also pay too cheap.

Better safe than sorry, go for branded choices because they often adopt the newest technology to enhance the overall lifespan and reduce any annoyance like a rattling sound.

Moreover, they come with a reliable warranty.
