Welcome to this blog post about the Best Canister Filter For 100 Gallon Tank! We’ll be reviewing seven different brands of canister filters and giving an honest opinion about which one is the best. 

We know how hard it is to find a good filter for an aquarium larger than 100 gallons, and we’re here to help take care of that tedious task. Our team has done all the research, so you don’t have to worry about spending days trying to figure out which model will work best with your needs- just scroll down!

Canister Filters Explained

As opposed to hang-on filters, canister filters are externally mounted and connected by intake and output tubing. In a canister filter, water from the tank is drained into the pressure chamber, where it is cleaned and disinfected. Various filter media can be used in this chamber. 

Compared to other filter types, a canister filter can force water directly through the media layers rather than around them, resulting in much-improved filtration efficiency.

However, a canister filter must be primed before it can be used. Most newer versions include self-priming systems, so you have to press a button and wait for up to 30 minutes for the filter to be ready to use. This is great!

Buying Guide – Factors To Consider For The Best Canister Filter For 100 Gallon Tank

Best Canister Filter For 100 Gallon Tank Buying Guide


Keeping your fish in a clean, chemical-free environment requires an adequate GPH rate for your filter.

Filters at least three to four times as large as the aquarium’s capacity are frequently recommended. For example, for a 100-gallon aquarium, a filter with a GPH of at least 300-400 would be necessary.

Filter Media

In the case of a 100-gallon tank, you need a filter that can handle all three types of filtering – chemical, biological, and chemical, respectively. For the most part, filters allow you to utilize your own filter material, although there are a few exceptions. 

You have many options here, so go with whatever suits your needs best. 

We’d prefer it if you went with a filter that lets you make your own filter media modifications. However, selecting a filter with a large capacity for filter media is vital.


The canister filter you purchase must be well-made to provide you with outstanding service over the long term. For the most part, most canister filters are constructed from plastic. No matter the canister filter you choose, make sure that the plastic used in its construction is safe and long-lasting.


Many consumers decide how much they are willing to spend on a canister filter in advance. Therefore, if you’re looking for the best budget canister filter, you’ll need to consider several other factors, including your financial situation.

Consider the various costs and filters before you decide to stick to your budget. Comparing different items can show you how much value you can obtain for a low price.

Buying canister filters online is a good option if you need them quickly. In addition to offering a wide range of reasonably priced but reliable canister filters, they’re an excellent place to start.
