Hang On Back Filters are a really great and affordable filtration choice for a wide range of aquariums. For aquariums in the 10-70 gallon range there are a wide variety of great Hang On Back Filters to choose from and I would say they would be our first choice for aquarium filtration. Even for tanks in the 70-120 gallon range, two hang on back filters can provide adequate filtration. They are easy to use and easy to replace the filtration. For tanks under 10 gallons internal filters are also available. Click on pictures to open a new link with current prices.
The granddaddy of all hang on back filters has to be the Marineland brand filters. They have been around forever and are our favorite without any doubt. They simply last forever, are extremely reliable, and their replacement cartridges are affordable, can be rinsed out a couple of times before replacing them, are super easy to change, and are available everywhere! I really like the with the new 350 model you can either use up to four filter cartridges or you can put a small UV or heater in the back of one of the sections. There are several different models and sizes to choose from.
Marineland Penguin Power Filter Rite-Size Filter Cartridges are an easy and convenient solution to keeping your aquarium clean. Rite-Size Cartridges feature Black Diamond Premium activated Carbon that works to trap more dirt and remove more impurities. Likewise, these easy-to-use cartridges deliver maximum water to carbon contact. Each Cartridge is color coded by size to make it easy to select the correct cartridge for your Penguin BIO-Wheel Filter.
Ok, so this is a UV Sterilizer and not a hang on back filter. We are putting it after the Marineland because it is only 7 inches long and will fit right in the back one of the Marineland 350 compartments effectively adding UV sterilization to your filter! We do not recommend continuous use of UV but it’s great when you really have persistent cloudy water, algae, or ich problems. It’s much better than chemical solutions that will disrupt your bacteria. If you use it continuously for a long time to cure a disease issue we recommend you re-stock the tank with Aquarium Microfauna afterwards.

The Aquaripure filter is a comprehensive biological filter which will completely process all organic matter and remove all nitrates in an Aquarium. The Aquaripure uses beneficial bacteria to break down invisible organic matter and nitrates completely into Nitrogen gas which then escapes into the atmosphere. This same process is even used by some water treatment plants to make wastewater safe for human consumption and to clean polluted water. The Aquaripure does this in an extremely safe and controlled environment and after the water from the Aquaripure is aerated there is nothing left but pure, clean, crystal clear water.
