How to Choose the Ideal Canister Filter for Your Aquarium

Wondering how you could set apart the best from the rest? Here’s the 101 guide to choosing the best canister filter- no better way to get a bang for your buck.

The Tank Size and Flow Rate

A feature that you must consider when choosing a canister filter, the tank size you settle for should be arrived at depending on the size of your aquarium. Be sure to read the description of the tank so as to be sure of the compatibility.

As for the flow rate, it is measured in Gallons per Hour. In this case, I’d recommend that you go for one that has a turnover of at least 4x the size of your tank. So, if you have a 100-gallon tank, you’ll go for a canister filter with a GPH of 400

Motor

This is basically what pumps the water into the filter so that filtration can take place. It’s therefore quite straightforward as to why you would need to have an amazing motor on your canister filter.

The type of motor you will get in most canister filters is the Epoxy type which is mounted on the head with the impeller upside down. This is preferable since it prevents any damage to the impeller from dust, moisture or debris. This kind of motor is sealed and it’s therefore quiet and demanding of less maintenance.

Besides the Epoxy motor, you could also get a magnetic-driven motor. The magnetic coil on this one functions to power the impeller. The difference to the Epoxy variant, however, is that these ones are self-priming and as such, you don’t have to siphon the water manually. On the downside, they aren’t’ completely sealed which could compromise their longevity depends on how well you take care of them

Valves

Canister filters normally come with two valves one of which functions to control the input while the other controls the output.

Now whereas most canister filters will have a valve that controls the input and output, what you’ll want to look for is one whose valves can be closed completely. This makes it easy when it comes to maintenance since the water will stay in the hoses and you won’t have to re-prime the filter whatsoever.

Impeller

For the impeller, look for one that has protection against debris. Since debris could result to the impeller hamming and damage the motor, in the long run, the best canister filter for you should be one with a seal, gasket or O-ring on the impeller which should then prevent it from damage.

Filter Media

At the end of the day, you’ll want to optimize on the filtration process and there’s no better way to do this other than by going for a canister with as much filtration media as possible.

As compared to one that has only one kind of filtration media, a canister filter with the mechanical, chemical and biological filtration media is guaranteed to give you much better results.

Stocking Level

The stocking level and flow rate of a canister filter are dependent on each other in the sense that the flow rate you want depends on how heavily stocked the tank is.

With more fish, for instance, you’ll want to have a high flow rate since the amount of waste produced is more. If you’ll be using it on your turtle, you’ll also need a higher flow rate as compared to someone who is using it simply on fish.

Conclusion

Without doubt, it’s much simpler and definitely more convenient to have a canister filter regardless of the size of your tank. At the end of the day, it’s all about efficiency and longevity which and I’m positive that the buying guide and best canister filter reviews should conveniently give you both of these.

One more thing, it’s important to go through the user manual during installation, maintenance and usage of your canister filter for optimal performance.
