Filter for a small aquarium

Owners of small aquariums from 5 to 50 liters often face the problem of finding a small internal filter for their reservoir. The problem is that you need good filtration and aeration of the aquarium, but at the same time, the filter should not create a strong flow so that the fish and the plant will not blow away.

In this article, we will give recommendations on choosing and using mini-filters.

And you need to start with the fact that an important role in the life of an aquarium is played by the soil, especially in small aquariums, where the biobalance is easily broken. Soil should be neutral, lightweight, porous, laid 5-7 centimeters thick. All these conditions will not worry about the biological filtration of the aquarium because they will develop well in such a substrate. colonies of beneficial bacteria nitrifiers and other organisms involved in nitrogen cycle. And, as you know, the lion’s share of biological processes occur in the ground! We can say that the primary filter in the aquarium is the ground, so pay special attention to this issue.

As for the filters themselves for small aquariums, there are three options: mounted filters, waterfalls, mini-filters with a glass, aerlift filter. Consider their advantages and disadvantages.

Mounted filters for aquarium

This is a kind of compromise between the desire of an aquarist to establish filtering and the physical impossibility of shoving anything into a mini-aquarium. These filters are called "backpacks" or "waterfalls." This filter is best suited for small aquariums, when in the amount of 5-10 liters any internal filter will be superfluous.

Waterfall filters come in two varieties: internal and external. The internal waterfall filter is installed inside the aquarium – it is completely in the aquarium, the external one is respectively hung on the outside of the aquarium. Taking into account the specifics of the topic, we are more interested in external mounted filters.

The advantage of these filters is that they create a minimum flow in the aquarium, which is reproduced by a falling stream of water, at the same time such flow is enough for aeration of a small aquarium.

Among the shortcomings can be called the inconvenience associated with filling the filter with filtering materials, for example, coal, zeolite.

Mini Fish Tank Filters

Perhaps the most popular and popular filters for small aquariums. For example, internal filter Laguna KF , which we have recently reviewed.

How convenient are these filters ?! They have a “glass” where you can place various fillings, depending on the situation that has developed in your mini-aquarium. When choosing, pay attention to the equipment, for example, the presence of the nozzle of the flute, it will help you reduce the flow. Also, it is desirable that the filter nozzle is rotated to the sides – this will also help you minimize the flow, if necessary. Pay attention to the size of the glass, even though the aquarium is small, yet the filter is a filter. A small compartment for filter elements, in fact, eliminates all filtration capacity. It turns out the pump, not a filter.

Airlift Fish Tank Filters

The so-called airlift filters should also be referred to the internal Fish Tank Filters. The principle of operation of these filters is based on the movement of air under water. Air bubbles rising to the surface create cravings in the air vent tube. Water, passing through the filter material under the action of this thrust, is cleaned. The advantage of such filters is that they combine the functions of the filter and the aerator. The disadvantage is the noise of the murmuring water.

As a rule, they are used in a spawning aquarium, for raising fry.

At the end of the article, a small life hack. If your filter is “blowing hard”, there is no flute, the nozzle does not turn … you can use a suction cup plug from an external filter. It looks like this.

Reducing the flow of the Fish Tank Filter

The plug is inserted into the nozzle into the thrust and strongly extinguishes even the flow from 1200 l / h You can apply something else that creates an obstruction to the flow, but not a closing nozzle (otherwise the water will go through the aeration tube).
