What is a HOB Filter?

A hob filter is otherwise known as a hang on back filters. This is the most popular type of filter out there when it comes to choosing a reliable aquarium filter. They are popular because they are easy to install and highly effective. They require very little maintenance and care and can pretty much take care of the work without a lot of effort on your part.

If you didn’t guess from the title, these filters hang on the backside of your aquarium so you can still appreciate the full view of your fish and anything in your tank from the front. These filters are simple, which means they aren’t overly bulky and they are versatile from tank to tank.

The best hob filter works using an intake tube that pulls water from the tank into the filter. The water processes through the filter inside the casing. It might use a sponge or another material inside there to filter. Once it has filtered, the clean water goes directly back into the tank, almost like a waterfall. This is an ongoing process with water continually going in and the clean water coming back out and mixing. This process also oxygenates the water.

Hob filters come in all different styles and sizes. You will see some top rated hob filter options that let you change the water flow if you prefer, among other things.

Buyer’s Guide to Filter for Aquariums

Tetra 20 Gallon Aquarium Kit

Before you make a final decision on the model that works best for your aquariums, we have a few tips and useful details that might just help you make an educated decision. We’ve put together a simple buyer’s guide to give you some insight on what hob models should offer and what you might want to keep in mind for your use as you make a decision.

Remember that all of the models here made it this far for a reason. Not every aquariums needs are the same and what you need could greatly vary from what another owner may need. Some people have five specialty fish while others might have 50 gold fish. The use could define the model that works for you. Don’t purchase just because you recognize the name but rather because you find one or two favorites that seem to work the way you need them to.

There may be a specific feature you’re looking for on products or a variety of features. Whether you have a tank that needs 40, 80, 110 or more gallons, there is sure to be a suitable product here for most users in terms of sound volume, performance, technology, and the ability to clear contaminants. The brands are not always a primary piece of information but something to keep in mind.

Value for the Money

There are some high dollar product options out there. We made an effort to address multiple price ranges in this article but as a participant you should be prepared for your budget range so you can spend within your money budget.

At the same time, you want to get something that is good value for the money. Here are some specific things that your contents should offer in fact for all users.

  • Reliable performance
  • Intuitive technology
  • Reasonable sound volume – the quieter the better
  • The number of gallons the housing can handle in reasonable time
  • Ability to clear debris matter and impurities effectively
  • Instructions that are easy to follow
  • Truly hangs on the back wall
  • Easy to maintain with tubes, wheels, filters, and everything.
  • Filter replacement and care
  • Total customer experience and comment

These are just general things that are something every machine should cover in some way. They may not always be uniform in all factors but in the end, all of the steps matter in some way and the casual browser will care about these details.

There is a certain advantage to manufacturers who appeal to the overall effect of their equipment device, giving hobs their full attention for customers and delivering according to their reputation as well.

Flowing Rate

When it comes to looking at the device picks, you will see mention of flow rate on all of them. While a specific rate may not be defined, the goal is to know the functionality to maintain a flow rate or adjust it exists.

Some hobs have a fixed rate for convenience and that rate is typically simple and steady without being too heavy for feeding but reliable enough that someone doesn’t have to manually clean the tank once a week.

Some choices by comparison offer a device that lets you adjust the rate on your device based on what you need at the time. You can set it at super speed or high power to get quick results or you can slow it down for feedings and not have to worry about wasting food at feedings because the impellers and tubes suck it all in right away.

The goal is to be able to complete this note without being completely manual or working about buildup as one of the drawbacks for the function.

Media Filtration Output Ratings

This particular terminology ultimately refers to the process or the idea of cleaning out impurities and imbalances from the water while still keeping proper oxygen levels on track for the creatures and species within. Some filters have limitations as to what they can clean away or how quickly they can clean away while others clean everything for beauty and forget that some good bacteria serves a purpose.

The truth is, you need a good balance. You want to be able to keep the bottom clean and not have to worry about a spot of nasty accumulation anywhere on the tank but you also want the living environment to be realistic and healthy for your fish.

Look for excellence in this department to avoid a headache later when your biomax hob or whatever filter you end up with isn’t quite living up to your expectations. Remember this might not be the same for everyone and there is good bacteria that can have positive action within the tank.

PH levels, bacteria, and oxygen must be balanced. You do want to filter out waste, toxins, and impurities without a doubt but remember there are benefits to some nitrates within the water to avoid other problems.

Required Maintenance

One of the first things you might want to review is the stuff that requires extra care from you. Rocks and other items might get caught in the line and they can get lodged in bucket or baskets of the hobs, leading to a lack of air for filtration or even a full shut down of the motors on the devices.

If you’re a beginner, you may think that you can set the filter and forget it. While some devices might have this advantage most of them will have a layer that requires maintenance and cleaning to keep them operational so there isn’t an issue for the inhabitants in the tank later on.

The majority of the time, you filter may run seamlessly without leaks and provide the perfect oxygenation but hobbyists will agree that with any model it is always possible for a rock or some other debris to get lodged in the filter stores and cause it to shut off or become clogged.

Find out what type of routine maintenance or cleaning might be required and this could be a comment to consider among other factors to be sure you get the experience you are looking for.

No matter whether you have sponges, basket, or other methods, you will have to do some cleaning and filter changing at times to prevent breakdown of the machine and avoid trouble as time goes on.


If you’re going to use a hob method to keep your spaces clean, you want to know it is going to last. While some of these forms are more affordable than others, you can bet that even the most inexpensive options need to provide durability for your aid.

Don’t be afraid to check out comments from other users to get a real feel and lots of helpful information about the overall quality and durability of the hobs in question. This purchase probably isn’t made lightly. You’re making it to complete a task that needs handled and you need it to reliably last rather than worry about a breakdown the second day of use.

Technology Solutions

If you want all of the bells in whistles, you’re in luck! We have both simple options here as well as solutions that have benefits of the most advanced technological methods on the market. Technology offers depth to your solution and can be impressive but sometimes it also costs more.

The prices often reflect the capabilities and functions of the hob filter and your purchase may make a difference when they are on the leading edge as far as the newest and latest or maybe even the first to aid in certain ways is concerned.

Technology is nothing without having the right construction to support the addition of such features so just keep that in mind.

Tank Size

Another important factor for choosing hob filters is the size of your aquarium. Obviously, you should plan to get a filter that accommodates the size of your tank and operates at a GPH that will truly work for the space.

A lot of these are designed for small to medium tanks but there are some large capabilities from some brands as well. Look at the filtration media specifics and know that it will truly accommodate your tank. If your tank is not filtered appropriately, you risk the health and safety of your fish so choose wisely and pay attention to the details in the process.

There are some larger sizes out there so just be sure that you pay attention to this detail. It is also not uncommon for people to pair multiple HOBs on a larger tank at each end in order for the filters to work their magic together.
