Outside Power Filters
For aquariums there are basically 3 types of aquarium filters you can choose from:
1. Outside Power Filters
2. Undergravel Filters
3. Canister Filters
Outside Power Filters-
Outside power filters are ones I like to use on my aquariums. They are easy access and works great at keeping my water crystal clear. Outside power filters are the ones that hang on the outside of your aquarium. How they work is that they have a motor in which it draws water from your aquarium through a tube to inside your filter which contain filter media. Here is where all the dirt, debris, fish feces are the trapped inside in which your beneficial bacteria will begin to grow and break down harmful ammonia and other dissolved gases. I have been using these types of aquarium filters for years and have had great results with fish keeping. A good one I recommend is AquaClear Filters by Hagen, they come in a variety of sizes suitable for all tank sizes and shapes.
