Horizontal Filter For A Small Aquarium

Aquarists, especially beginners, are bound to face the challenge of filtering water. An aquarium, a living organism, and if you let it run free, it will die. The most effective filter is sandy. How sand grains manage to destroy harmful substances-metabolites and leave necessary for the life of fish and plants is not known. Usually, a sand filter is made portable, i.e., a place outside the aquarium is determined for it. The schematic diagram of his work looks like this:

Water from the aquarium is pumped using a special pump or airlift. In the airlift, air bubbles from the compressor serve as a vehicle for water. Making such a filter is a laborious business and not everyone can do it. But, as practice shows, the problem has a solution and the effect is quite acceptable. The schematic diagram of the simplified filter looks like this:

Such a filter is good because it constantly pumps water through the soil in the aquarium and does not allow it to silt. For plants it is very useful.
Now, after a brief theoretical introduction, let’s get down to business.

Three basic things are needed to make a filter:

  • not very dense foam rubber;
  • a piece of garden PVC hose;
  • tubular aquarium sprayers.

We cut a strip of foam rubber 3x3x45 cm in size. The length may be different and depends on the size of the nozzles and the overall design of the aquarium. And the section length x width should be 1.5-2 cm larger than the diameter of the hose.

In a strip of foam rubber we cut a groove under sprays. We make cuts to a depth of 1-1.5 cm.

Foam from the groove is convenient to cut with ordinary scissors.

The result should be such a blank. In the future, in the groove take their place sprayers.

Now the largest foam blanks cut a piece of garden hose.

Cut the hose along the entire length. Make it convenient and safe with scissors.

We will make holes in the hose with a hot awl. It is necessary to heat up the awl in order that the holes may be tightened.

Holes need to be done often very close to each other. You can do two or three rows.

In order to fix the filter at the bottom of the aquarium will need suckers. We will sew them with nylon thread or fishing line to the foam rubber blank.

In this case, three suction cups will suffice.

In the foam groove we place the dispensers.

From above on a design we will dress a hose.

It should make something similar to the design shown in the photo. We end the ends with pieces of foam rubber so that the air escapes through the holes above.

We connect the compressor and install the filter on the bottom of the aquarium.

Bubbles of air rise to the surface of the water and carry with them particles of water. The flow of water entrains the water turbidity and leaves it in the filter elements.

From above the filter can be decorated with aquarium soil. Soil (coarse sand) will be the main element of the biofilter. On the edges of sand grains with time, bacteria will settle. These bacteria feed on metabolites harmful to fish and plants. Thus, the biological balance of the reservoir will be maintained for a long time. In small aquariums, filters of similar design work perfectly and do not spoil the landscape, since they are practically invisible. Air bubbles in the background create a fabulous screen, making the whole picture of the underwater world only wins.
