Our Comprehensive Buying Guide
Because we know just how hard it can be to decide on an external canister water filter for your 100-gallon aquarium, we have done extensive research to provide you with top-tier products that provide the best quality/price ratio. After carefully comparing many popular models and reading what customers had to say about them in countless canister filter reviews, we have decided to write a short guide so that you don’t have to put the same amount of time and effort.
Here are some basic things you may want to learn about canister filters suited to aquariums of up to 100 gallons as well as a few aspects you may want to take into consideration before buying.
Canister filters explained
Contrary to hang-on filters, canister filters don’t take up space in the tank but are placed externally, the connection being made through intake and output tubing. A canister filter will take water from the tank through a tube and run it through a pressurized chamber. That chamber can contain various filter media. The best part about a canister filter compared to other types of filters is that water is forced directly through the media layers and not around them, providing for a much more efficient filtration.
However, you can’t just start up a canister filter, you need to prime it first. The good part is that most modern models come with self-priming systems which only require that you push a button and wait for up to 30 minutes before the filter is ready to use.
Make sure your model has a high enough flow rate
Since we’re talking about a 100-gallon aquarium, which is rather large, the flow rate is an extremely important aspect when deciding on a filter model. You want to make sure that the filter has a good enough flow capacity, otherwise, you’d need to manually replace 20 percent of the water in the tank every few weeks. A flow rate of over 300 gallons per hour would normally suffice since it would be able to filter 3 times the volume of a 100-gallon tank in just an hour. Just remember the fact that flow rate values are usually for clean filters and hoses, and you might want to go for a higher flow rate to make sure the device can still pump enough water even when you don’t have enough time to clean it.
A bit about filters
Contrary to hang-on filters, canister variants come with customizable filter media, which means you’re not stuck with the pre-made manufacturer design. You can add and replace activated carbon cartridges, bio-balls, ceramic rings and other types of filters. The more filter media a model has to offer, the better, especially when you can fully customize the setup and ensure that your aquarium gets the best filtration treatment possible.
Also make sure that you stack up on new filters from time to time, as dirty filters don’t just lower the performance of the device, but also run the risk of contaminating the water when they are filled with too many impurities and chemicals.
