When you search for aquarium supplies, you should never ignore the Aqua Clear products. This is a typical manufacturer in the field of providing aquarium products and always receives high praise from customers. And this filter of the company is also one of the products that many people trust.
This filter has many options so that you can choose one that fits your tank size, it can integrate with tanks from 20 gallons to 110 gallons.

The filtration time will be longer so that it will have enough time to remove all impurities and decompose ammonia. And don’t forget that pathogenic bacteria or nitrites will also be removed through this filter.
You can also adjust the water flow of the filter easily while not compromising on the quality of the filter. Changing the water flow makes it easier to care for and clean the tank, but this change only allows the speed of the water to change and does not affect the filter’s ability to remove impurities.
This filter is also easy to install and maintain, and you can easily replace the activated carbon packages that can be purchased at any aquarium store. Quiet and affordable running engines are outstanding advantages of the product.

The water in the aquarium will go through 3 stages of filtration to give the best results. This three-stage controller is very powerful, completely eliminating dirt and harmful bacteria. Especially, the bio-wheel is not only capable of biological filtration but also has the role of providing more oxygen to the aquarium.
The Rite-size filter box filters dust and debris, and it can also disperse ammonia. After the water has gone through this first step, it will be passed through activated carbon to remove impurities. And finally will go through the bio-wheel.
With three such filters, this filter ensures the water in the tank will be completely removed from dirt and impurities. However, the downside of this product is that the bio-wheel is not always moving and it is only for tanks under 70 gallons.

You can also adjust the flow rate to suit the conditions of the fish in the tank, as well as to make cleaning the tank easier. The ability to adjust the water flow is essential and is the element that every filter should have. For small fish, for example, the large flow of water will make them scared and will not be able to swim comfortably.
This product is also a three-stage filter so the water in the aquarium will also be carefully filtered. The three filter layers are sponges, activated carbon and finally quad bio-falls.

This patented filtration system will give amazing filter results to aquarium owners. It is also considered the best HOB filter for a 10-gallon tank.

Activated carbon is the third filtration stage, where the water will be removed impurities and harmful bacteria. This is followed by bio-screens and finally C-Nodes, where beneficial bacteria will grow and break down the structure of ammonia and nitrate.
The engine of this filter is really smooth and quiet, although it works very hard but hardly creates a sound that scares the inhabitants of the tank. It also has an indicator to let you know it’s time to clean the filter.

How to choose the best Hang On Back filter?
The HOB filter is a filter that brings the best experience to customers, so it is becoming a popular choice. The hang on back filter does not require you to spend a lot of time to clean and maintain, the fact that it hides behind the tank will also help your tank with a more attractive appearance.
Those are the most common reasons that you should invest in a HOB filter for your aquarium. However, if you do not have much experience when investing in a filter, please refer to our buying guide below.
Here are the criteria that you should consider when choosing the best HOB filter:
#1 Flow rate
Many people do not care about the speed of the flow but this is one of the important factors that you should consider when choosing a HOB filter. The fast or slow flow rate not only affects the filtration capacity of the filter, but also directly affects the residents in the tank.
A flow rate that is too small will not cause dirt and debris to flow through the filtration stages. An excessive flow rate will affect the small sized aquarium inhabitants and scare them.
Therefore, you should choose filters that can adjust the flow rate so that you can choose the appropriate speed for your aquarium. And do not forget to consult the manufacturer’s information about the minimum and maximum speed of the filter for the best experience.
#2 Biological filtration
Filtering is also important for any filter, especially for biological filtration. Check to see if the filter you are going to choose has good bio filtering capacity, the more bio will give you the most perfect filtration results.
You should remember that even a small drop of fish needs a lot of good bacteria to handle. These bacteria can break down ammonia or nitrate, maintaining a clean and healthy living environment for tank residents.
Filters with many stages of filtration and outstanding biological filtration are always a top priority that you should keep in mind.
#3 Additional features
Additional features are not available for every filter, but they make it easier to maintain the filter and maintain a clean living environment for the fish.
A HOB filter with indicator that signals whenever the filter needs to be cleaned or it is clogged will be a great additional feature. Some may signal with lights, others use sound to signal. But whatever the filter indicator is, it’s a good feature.
Besides, a filter capable of self-priming is also not a bad choice. It will automatically fill the filter with water without any manual action from you.
The most expensive filters are not necessarily the best ones. Some well-known brands maintain a premium price, but some products work just as well, but at an affordable price.
So you should not just search for luxury brands, but expand the search area to be able to choose the most suitable product. You can also refer to HOB filter reviews of previous customers to optimize your search.
A HOB filter not only keeps your aquarium in good condition, but it also brings the best experience to the owner. You will save a lot of effort to maintain the filter as well as clean the aquarium. Not only that, your aquarium will look cleaner and more beautiful with a filter hanging from the back.
When choosing a hang on back filter, you should consider a number of factors to be able to choose the best one. Careful research will become a valuable gift for your hard work.
