You've already had the canister filter vs power filter debate and have decided that a canister is the one for you. So, now you’re probably thinking, okay, now what? Well, never fear! We’ve researched a variety of best-selling and brand new products to put together our canister filter reviews. Before we get to that, let’s take a closer look at some of the most important features you need to keep in mind when shopping for your fish tank filter setup.
Capacity - This is the measure of how much tank a filter can handle. For our purposes, the number we give you is the maximum number of recommended gallons a canister filter can handle. Don’t worry! There’s a wide range here.
Pump Output - Pump output is measured in gallons per hour and tells how fast the water cycles through the pump. Ideally, it should be 4 times the volume of the tank. That means that the water will cycle through 4 times every hour.
Accessories - We consider a canister filter to have accessories if it has any extras included. Most of the time, this means that filtering media is included. Sometimes, it’s just the right amount you’ll need to get started.
Quiet - None of our best aquarium canisters filters are loud. That’s not a desirable quality in an aquarium filter. Some are louder than others but, for the most part, they’re pretty quiet. Or else they might not have made the list.
Dimensions - This is important if you’re planning to put your canister filter in a cabinet or try to hide it in some way. You should have some idea of where you’re going to set it up and how much room you have.
Warranty - Obviously, the longer the warranty, the better. These filters all have moving parts that can break over time. Make sure you know what is covered and, in most cases, what isn’t covered. You don’t want any surprises!
Finding the right canister filter is no easy task, but you should always remember that your fish depend on you to give them a clean, healthy environment. In some cases, you turtles do, too. Don’t let your pets down. Now that you know what to look for, let’s take a look at our canister filter reviews. Short on time? Make sure you check out our top and budget picks first.
