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: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: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 are needed to produce the filter: br>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.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. As a result, you should get this kind of workpiece. In the future, sprays will take their place in the groove.
