Things to Consider Before Buying a Canister Filter

A canister filter is a necessary component for any aquarium and water tank. Without it, your precious marine life would die because of the accumulation of dirt and debris.

Of course, it would hard for you to manually change the water of your tank from time to time. Just imagine the hassle that it will give you.

Once you have decided to get a canister filter, it is time for you to head to your local stores on online shops. It is a guarantee that you will see a lot of brands and varieties.

But which of them should you choose? Do you even know what makes a good canister filter? Worry not. We got all the answers to these questions.

Flow Rate

It will be a bad move if you choose a canister filter that has a low flow rate. If your filter has a poor flow rate rating, then it could not clean your aquarium quickly and efficiently.

Moreover, a filter that runs slow will consume too much power. Therefore, it might be the reason for the increase in your energy bill.

Meanwhile, a good canister filter can process the water of an aquarium for as quick as 300 gallons per hour. Some brands can even go up to 500 gallons per hour! They should be your primary choice since they won't waste your time and money!

Media Selection

A quality canister filter should be able to accommodate multiple filter media at the same time. Otherwise, you won't be able to come up with a comprehensive filtration system.

When you shop for canister filters, you'll see the descriptions the types of media they can cater. The much, the better.

But it will always remain your responsibility to know how of each of these media work. After all, you won't be able to maximize the full potential of a certain media if you don't how to properly use it.

Improper usage of filters could also lead to possible damages on the canister.

Installation Process

There are a lot of canister filter brands that are notorious for being too rough on their users. Specifically, we are talking about the installation process. We all know that most of you are new to canister filters.

Of course, these machines are not your ordinary day-to-day appliances. Therefore, installing and using them would be difficult unless you have a manual.

A good canister filter has a comprehensive user guide. It should be well-written so that details like assembly and parts would have a clear direction.

Meanwhile, the ideal canister should have a self-priming mechanism. In this way, you don't have to siphon the aquarium water on the canister manually. Doing such is totally repulsive!

Easy to Clean

The job of a canister filter is to clean your aquarium, right? Therefore, it is very obvious that its internal parts will accumulate all sort of dirt over time.

If your filter is hard to clean, then you wouldn't be able to conduct regular maintenance properly. Moreover, it will eventually lead to the deterioration of your canister filter.

If we were you, we would choose a canister filter that can be disassembled. In this way, you can clean each part thoroughly and quickly. Once it's clean, you can be able to put back all the pieces together.
