Top 10 aquarium filters

Pet supplies

An aquarium is a small artificial reservoir with a closed space, in which there are no processes of natural purification of water from the waste products of inhabitants. As a result, the water is polluted with waste, a population of small algae, pathogenic bacteria grows in it, and the environment becomes destructive for the life of fish.

The purpose of modern filters has gone a little further than in the first stages of development. Now each advanced device is able not only to eliminate pollution, but also to provide a constant influx of beneficial bacteria and microorganisms, as well as to mix water layers, maintaining the temperature balance and the amount of dissolved oxygen that are optimal for fish.
