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 for sure. Usually, a sand filter is made portable, i.e. a place is defined for it outside the aquarium. The schematic diagram of his work is as follows:
 filter for a small aquarium
Water is pumped from an aquarium using a special pump or airlift. In the airlift, air bubbles from the compressor serve as a vehicle for water. The manufacture of such a filter is labor-intensive and far from everyone can. 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:
 small aquarium filter
This filter is good because it constantly pumps water through the ground in the aquarium and not allows it to silt. For plants this is very useful. Now after a brief theoretical introduction, let's get down to business.
 three basic things
Three basic things are needed to produce the filter: br>
  • not very dense foam,
  • piece of garden PVC hose
  • tubular aquarium sprayers
Cut a strip of foam rubber
Cut a strip of foam rubber 3x3x45 cm. The length can be different and depends on the size of the nozzles and the overall design of the aquarium. A section of the length x width should be 1.5-2 cm larger than the diameter of the hose.  cut the groove under the sprayers
In the strip of foam rubber cut the groove under sprayers. We make cuts to a depth of 1-1.5 cm. Foam from the groove is conveniently cut with conventional scissors.  such a blank As a result, you should get this kind of workpiece. In the future, sprays will take their place in the groove.
 cut off a piece of garden hose
Now for the size of the foam piece cut the piece of garden hose.
Cut the hose
We cut the hose along the entire length. Make it convenient and safe with scissors.
 shilom we'll do in the hose
We'll make a hole in the hose with a hot shil. It is necessary to heat up the awl in order for the holes to be tightened.
 Holes need to be made often
Holes need to be made often very close to each other. You can do two or three rows.
 fix the filter on the bottom of the aquarium
To attach the filter to the bottom of the aquarium you will need a suction cup.We will sew them with a nylon thread or a fishing line to the foam rubber.
 three suckers will suffice
In this case, three suckers will suffice.
place the nozzles
Place the sprays in the foam rubber groove.
 we shall dress the hose
C We will put a hose on top of the construction.
 End the ends with pieces
Something similar to the design shown in the photo should turn out. We end the ends with foam rubber pieces so that the air goes out through the holes at the top.
 set the filter on the bottom
Connect the compressor and set the filter on the bottom of the aquarium.
Bubbles air rise
Air bubbles rise to the surface of the water and carry particles of water with them. The flow of water entrains the water turbidity and leaves it in the filter elements. decorate with aquarium primer 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.
