Types of aquarium filters their pros and cons.


When we decide to equip an aquarium in our home we will have a few questions regarding the equipment that we want to install in our aquarium.

A filter that will carry out mechanical water purification, a mandatory equipment without which the life of our aquarium or rather its inhabitants both hydrobionts and plants may be in jeopardy.

Passing through the absorbents the filter material which is overgrown with beneficial anaerobic bacteria the water is purified.

Filters can be divided into two main types and several subtypes.

The main types I would single out are active filters connected to the mains in which a water pump is installed and passive filters that operate offline but in any case they are energy-consuming because they are supplied with air through a compressor operating from the mains although this is more economically.

So Active filters and their subtypes:

Submersible filter.

Submersible filters are installed below the upper water mark in the aquarium they take water through the filter material such as foam of different fractions and eject the purified water creating a rather powerful stream of water. which I would consider to be its disadvantages.

A strong current is a friend of filamentous algae, a protozoan that can ruin the look of your aquarium with live plants, therefore you need to look for an opportunity to reduce the flow of water for this they use various nozzles that can come with a filter they look like a flute and dump water small streams you can arrange something like a waterfall.

Of the advantages one can note a fairly affordable price ease of use durability with proper care for it interchangeability and maintainability.


Canister, external filter.

The second type of active filters which is installed outside the aquarium.

This filter is good because it has high performance, does not take up space in the aquarium you can install several types of filter material of different fractions, it is equipped with many different kinds of nozzles for discharging water to the aquarium.

Of the minuses the high price the repair is quite problematic sometimes the fixing latches break and this issue is extremely difficult to solve I speak from my own experience.

The latches are sometimes very difficult to open and it is not easy to separate the housings and the top from the pump.

But these filters do their job perfectly.


Waterfall type outdoor filter.

I liked using this filter in small aquariums where I didn't need water flow.

The water is taken in by a pump and rises into the hopper with filter material from where it falls back into the aquarium like a waterfall.


Passive filters.

This filter works by sending air through an air hose to an atomizer mounted inside the filter and rising air bubbles create an upward flow of water that passes through the foam sponge.


Here is another option for a passive filter filled with synthetic winterizer this is a great option for a spawning aquarium or for an aquarium where you grow fry and fish larvae.

If you do not know then a fish becomes a fry when it eats its entire yolk sac and begins to feed on its own and before that the fry is called a larva.
