The Most Popular Types of Freshwater and Saltwater Filters

To keep your aquariums clean and safe, a filtration system is critical. Here are the most popular types for saltwater and freshwater fish tanks.

Best for Saltwater Aquariums: Wet/Dry Filters

In a case of a saltwater aquarium, wet/dry filters are the best ones. We like them because they are capable for filtering a huge amount of waste, debris, chemicals and etc. They are perfect for aquariums with a lot of fish and other creatures.

One of the most useful and best-known filtration systems of this kind is known as the Berlin Method filter/algal system. It is extremely easy to use, but it still provides a perfect water filtration. Ammonia and nitrate levels are always as they should be and there is little risk of toxicity. Obviously, all of this can be met only if you make sure the proper flow is taken into consideration.

Other popular types are protein skimmers, deep sand bed and live rock.

Best for Freshwater Aquariums: HOB Power Filters

Almost all experts prefer and use hang-on-back (HOB) power filters for freshwater tanks. First of all, they ensure three-stage filtration (biological, chemical and mechanical). These filters can be used for tanks of various sizes, so replacing them when you replace your aquarium won’t be necessary. We also like the fact they hang on the back side of a tank, so none of the view will be obscured.

Other popular types of aquarium filters for freshwater tanks are undergravel, wet/dry, and canister models.
