What is a HOB Filter?

HOB (hang on the back) filters are among the most popular filters on the market. They are easy-to-install and maintain and are efficient and affordable. 

A HOB filter is a specific version of a power filter. The main difference lies in their low-maintenance and cleaning capacities.

This type of filter hangs on the back wall of your aquarium. Each HOB filter contains the filter body, the filter media cartridge, and the intake tube.

The filter’s cartridges act as the medium where filtration stages occur. Those stages are typically mechanical, chemical, and biological filtration.

The motor is usually incorporated in modern HOB filters, making cleaning easier and quicker.

Things to Keep in Mind When Picking a HOB Filter

 Size of Tank

Your tank’s size will determine the size and model of HOB filter you will need. Each HOB model will come with a recommended tank size. Most aquarists tend to size up in filtration levels to ensure enough water is filtered per hour. 

Most HOB filters are designed for small aquariums. Therefore they do not take up a lot of space and are easy to maintain. It is vital to keep the water in your tank filtered for your fish’s health. 

Filtration Media

Some HOB filters come with filtration media, while others allow you to add your own. Overall there are three types of filtration: chemical, biological, and mechanical.  

Do a little research ahead of time to decide what filtration will be best for your aquarium. This will help you determine which HOB filter will work best for your needs. 

Maintenance

In most cases, a HOB filter needs cleaning once a month. However, depending on the specific model, you may need to replace the media every 3 to 4 weeks. 

When cleaning your filter, be sure to clean the impeller as well. It is essential to keep the impeller in good working order to avoid debris getting lodged. 

Over time you will need to remove any algae or lime deposits from the filter housing. 

Finally, depending on the type of media you have, you may need to replace it with new media before restarting the filter. 

How to Set up Hang on Back Filter

In general, HOB filters are extremely easy to set up and install. 

First, you will need to choose the right sized filter for your tank and decide where to place the filter on your tank. 

Second, you will begin to assemble the filtration media. Follow the manufacturer’s instructions for your filter. If you add your own media, make sure it is compatible with your filter. 

Third, you will install the intake sump.

Finally, hang the filter on the back of your tank. Be sure to prime your filter before turning it on. 

How to Clean Hang on Back Filter

Cleaning a HOB filter is relatively easy. Once a month or when your filter starts to get dirty, you should use fresh filtration media, a small pitcher, and a bucket.

Unplug the filter and clean all the pipes, chutes, and tubes. Take out the sponge and rinse it well in a bucket of old aquarium water. While the sponge is out, you should replace the filter media.

Clean the motor and impeller if needed. It is good to add a lubricant to the motor to keep it running smoothly. 

Reassemble the filter and hang it back on your aquarium. Plug the filter back in and turn it on. 

HOB vs. Canister Filter

When comparing a HOB filter with a canister filter, you will first notice a significant difference in size. Since canister filters are external devices, they usually are larger and take more space outside the tank. Therefore, canister filters are more ideal for larger aquariums. 

On the other hand, the mobile and compact HOB filter is space-saving. A HOB filter’s size and capacity make it suitable for small to medium tanks. 

Installing a new HOB filter is much easier compared to a canister filter. A HOB filter is also easier to clean. Particularly for those using a filter for the first time, the process of cleaning a canister filter on their own may be challenging.

In most cases, a HOB filter offers better filtration in its biological capacity. The only other type that can compete with HOB filters in this field is wet/dry filters.

HOB filters are generally easier to clean and maintain. They do not require frequent changing of the media. Overall, HOB filters are usually more affordable than canister filters in terms of cost.
