What Is an Aquarium Filter?
Having a fish may not be as easy and effortless as it seems. Despite having the right food and a fish tank spacious enough for your pet fish, you also should pay a lot of attention to the water. It should not only have the right temperature but also always stay clean. Even if it seems completely transparent, it still may contain microbes and bacteria that threaten your fish’s and plants' life.
There is a huge variety of different water filters you can find. The first difference lies in type: you can purchase internal and external ones. The internal type may be a bit tricky to install but it has a better performance. The external type provides decent results (though, not as good as internal) and is less expensive and easier to maintain. Apart from placement, these tools can vary in the type of filtration: mechanical, chemical and biological.
To help you with your choice, we have selected the top-ranked aquarium filters that can fit different budgets and needs. If you are interested in other gear for fish tanks, check out our review of the best aquarium heaters that will help you maintain the proper water temperature.
