A saltwater tank can be filtered in a variety of ways. Filtration is required in order to maintain your fish tank safe and healthy.

A HOB filter can be effective and useful. In this post, we’ll look at ten of the best HOB filters for saltwater aquariums.

OUR TOP PICKS

We totally value the time of each consumer who is looking to purchase a new filter so if you don’t want to go through the whole article and you are in hurry then don’t worry as we have provided these 3 top picks from the entire list which you can purchase blindly.

What Are HOB Filters and How Do They Work?

The hang on back (HOB) aquarium filter, as previously said, is simply a filter that hangs from the rear of your tank. So, why would anybody want a large, heavy filter hanging off the rear of their tanks in plain sight?

For a variety of reasons, including the fact that: 

  • They are easily available.
  • The filter media is easily removed and changed.
  • Simple to keep up with.
  • They are low-cost.
  • They have a high level of filtration.  

Furthermore, technology has advanced significantly over the years, and many hob filters are now much quieter than previous models. If you have any tanks set up in peaceful areas, such as a bedroom, it is ideal. It’s crucial to remember, nevertheless, that one disadvantage of the hang on back filter is that the beneficial bacteria colony is destroyed each time the cartridge is changed. Despite this flaw, HOB filters are still a great choice for a high-quality filtering system. If you’re in the market for a new hob filter or this is your first, we want to put your mind at ease.

A HOB filter works by sucking water from your tank into a recirculating water pump, which then forces the water through different filter media and back into the tank.

Let’s take a closer look at how it filters the water in your tank one step at a time.

  1. The driven pump generates a magnetic current, which causes the impeller to whirl and centrifugally propel the water.
  2. Water is drawn up through the inlet tubes and into the pump by this pressure.
  3. The pump then forces the water through the filter material at a higher pressure.
  4. The purified water is then returned to the aquarium through a waterfall.

The Seachem Tidal Hang-on-Back filter offers a lot of power and a lot of room for you to personalize your filter material. On principle, the seachem tidal hob seems amazing, so I decided to put it to the test and evaluate it to other filter media in the genre. I was blown away, and I believe you will be as well. However, even though this filter is fantastic does not mean it is right for you. Continue reading to find out.

  • Features: This Seachem Tidal Hang-on-Back have following features as follow:
  • This filter uses an internal (inside-the-tank) motor rather than an exterior (outside-the-tank) motor. An internal motor does not require priming during installation or maintenance.
  • This filter will automatically start up for as long as the water level is over the threshold water line. It’s fantastic.    
  • : In a nutshell, bio media capacity is tremendous! The basket is rather large. This filtration system has more area for bio media than all the other four HOB filters I examined. In addition to being quieter than external motors, the internal motor offers another advantage.  
  • Clean the medium and put it in the rear of the filtration system, hang it on the back of the aquarium, and connect it to the power. A large plastic screw is also used as a levelling mechanism on the Tidal. It enables adjusting the filter level simpler than almost any hang-on-the-back I’ve tried. I particularly like how the screw isn’t readily driven off the filter, unlike other filter makers’ levelling mechanisms, which fall off if you simply look at them strange.
Pros
  • Great flow rate
  • Maintenance is easier
  • No priming is required
  • Durable design
  • Quiet operation
Cons
  • Does not have chemical media

Design of a basic HOB filter 

Every major tank supply manufacturer has its own HOB filter, each with its own range of attributes and price point. Learning the principles about how and why a HOB filter operates will make it much easier for you to select the best one for your tank. The filter box, a water pump, inlet tubes, and filter media are the essential design parts that all HOB filters include.

  • Filter box- A basic (mostly transparent) plastic box that hangs over the aquarium’s edge serves as a filter. The filter box’s interior area is used to store all of the filter material as well as the water that is filtered through it.
  • Water pump- Based on the model, this is usually linked to the base of the filter box or the water inlet. The majority of them have a magnetic impeller within. Before getting too technical, when electricity is given to the pump, the magnetic current produced enables the impeller to whirl and circulate the water.
  • Water inlet tubes- The main aim of these pipes is to send the water pressure further into the tank, resulting in greater water filtration and a smaller inlet flow area.
  • Filter media- Filter cartridges with foam pads (mechanical), ceramic beads or porous material media (biological), or maybe a carbon foam pad (mechanical/chemical) or a granular activated carbon bag (mechanical/chemical) are used (chemical).

Conclusion

The overall best HOB filter choice was SeaChem – Large Aquarium Fish Tank Filter, with Aqueon QuietFlow LED PRO Aquarium Power Filter coming in second as the greatest return on the money. The Aquatop Hang on Back Aquarium Filter is a more expensive option. I like elegant, practical filters with adjustable settings that can help your fish and invertebrates live in a healthier, safer environment.

FAQs

Are HOB filters effective?

Hang-on-back filters are one of the most common filters used by both amateurs and professionals. Their appeal stems from the ease with which they can be installed and maintained, as well as the fact that they are adaptable that can be used in a variety of tanks. To retain your tank’s water, clean as possible, most hob filters can provide all three phases of filtration (mechanical, biological, and chemical). These filtration systems may be cleansed and installed in less than about hour when it comes to cleaning.   

Is it possible to use a HOB filter for saltwater?

Yes, hang on back filters may be used in a saltwater aquarium. Most people would advise you to utilize a sump tank, which is just a bigger hang-on-back filter. The key is to make sure there’s enough live rock in the canister and that there’s adequate flow going through the filter and into the aquarium.
