Canister filters are self-contained filters that resemble a canister. These external purifiers are generally out of sight, maybe off to the side or behind a cabinet.

Canister filters are huge filter devices with a lot of power. They appear to be the most efficient and powerful devices available.

These filters operate outside of a tank. Only the tubing required for pulling in the water stays inside. The rest sits outside.

HOB filter

HOB stands for Hang On Back filter, also called power filter. These filters typically sit in the back of the tank, as its name indicates.

These filters are external. They do help to reduce the amount of room. The HOB is also simple to install. Simply lay them over the edge of your tank, switch it on, and there you go.

Water Paraments

The canister filter includes two tubes, one for the outlet and the other one for the inlet. The water travels in one tube via the filter's media and then travels back to the tank.


On the other hand, a HOB filter features a protruding intake tube that carries water into the filter from the tank's water. The intake tube pumps water into the HOB filter, traveling through the filter material before being pumped back into the tank.

Maintenance

It is essential to do regular maintenance on your canister filters. The brand, model, and type of filter used will determine how straightforward it is to maintain.


Before cleaning, you'll need to dismantle the pieces. It would help if you also thought about the media's performance.


When the media gets ineffective, it's time to replace it. Even when changing the filter media, you must follow specific processes for installing the filter material.


Cleaning is a massive issue with HOB filters since you must disassemble every few days to clear the build-up. Furthermore, you have to change the filter as soon as it starts to function poorly.

Price

Even when the capacity is about the same, the canister filter is typically more costly than the HOB. A canister filter cleans better than a HOB filter. Moreover, canister filters can function for long periods, thanks to their high-quality construction.


When you compare prices between stores, the price might vary dramatically. It would help if you also considered your purpose.


A HOB filter may be enough if you have a tiny aquarium. The best Hang On Back filter still serves your needs.

Water loss

Canister filters stay away from the top of the tank. This position reduces both evaporation and current. Hence, you don't need to worry about the water leaking.


On the other hand, using the HOB filter may result in water loss, especially when maintaining the tank. 

Pros And Cons Of Canister Filter Vs. HOB

It's crucial to consider the advantages and disadvantages of a filter before buying it. Canister and HOB undoubtedly offer some pros and cons, which we are going to mention.

When to choose the canister filter

You should employ a canister filter if your tank is more significant than 50 gallons. They can manage a larger volume of water while preserving excellent conditions.

Choose the HOB filter if your tank is too tiny and their added expense makes them unaffordable in most circumstances.
