What To Look for While Buying the Best Canister Filter: Everything You Need to Know
A quality canister is one that has all of the good stuff from low power consumption to noiseless operations, a better filtration setup, and improved motor ability. The key to keeping your aquarium nice and clean is to have a filter that is suitable for you. Thus, here are some things that you should consider while buying the best canister filters;
What is a Canister Filter?
Canister filters are one of many options available used for cleaning and maintaining an aquarium. These are self-contained devices that come in a box design and help you in conveniently filtering and exchanging the water all along. These filters work externally by using a series of pipes and pushing water through the filter to make it long-lasting and efficient.
Many contemporary models come with a built-in pump system that passes the water through these things to create enough pressure for cleaning it. Depending on the size of your aquarium, you can also include gravity-feed systems and extra pumps to enhance the filtration process. Also, the fact that they work amazingly irrespective of the water (salt or fresh) makes it a popular choice among others.
Advantages of a Canister Filter
There are a number of benefits when it comes to canister filters. Some of them are;
Adaptability as these things come with a remarkable and unrivaled three-step filtration system. Having mechanical, chemical, and biological filtration, these devices are highly efficient and help you with a great alternative. Hence, it not just only improves the quality of water but helps you in ensuring a long and healthy life of fish.
Straightforward Cleaning because they are equipped with an easy and convenient setup that helps you all along. These things usually come with two valves that make the overall disconnecting process even easier. So, you can ideally clean and replace them without being troubled by the process.
Better Flow Rates are another advantage of these canister filters that help you in making the tank long-lasting. As the device is processing the filtration exceptionally well, you will find these things highly efficient and quick. So, it takes less time to improve the quality of water, even with manual cleaning.
Flexible Setups are relatively versatile and include customize elements such as additional pumps, adaptors, media trays, and so on that you can set according to your needs. You can also utilize UV filters that will enhance the filtration system if you have a large tank that needs extra care and maintenance.
Apart from this, you can also find many other benefits of using these canister filters, such as noiseless operations, energy efficiency, easy setup, and so on, making them stand among other competitors in the market.
Aquarium Size
The first and foremost important requirement while buying a quality canister is choosing an aquarium that can effectively cycle the tank. For this purpose, apart from looking on the website, try considering the GPH range of the tank you are interested in. GPH or gallons per hour is the overall cycle or filters your desired tank can offer you after every hour.
Here, it is significant to consider the efficiency of your canister filter as it can highly influence the overall filtration your tank is processing. Try to look for something that is at least four times the volume of your water to use the canister to its full potential. In other words, I would suggest you go for 80 GPH for a smooth experience and an improved filtration process.
Type of Motors
The motor is another important feature to consider when it comes to a canister filter as you need something that can run smoothly for the whole day. So, it becomes important that you buy a motor that is durable, efficient, and doesn’t overwhelm you with the monthly bills. Hence, you can go for a canister filter that is approved by UL ratings and is constructed as per their standards.
In the market, you can find two types of motor, one being Epoxy sealed motor and the other magnet-driven motor. First of all, the epoxy motors are the most common for these filters that are mounted upside down and prevents any damage (in terms of moisture, dust, and debris), making them highly efficient for long-term usage. This motor works by spinning the magnetic coil around the impeller. Hence, water runs through the filter with minimum noise and provides you with little maintenance.
Secondly, you can find the magnet-driven motor that uses the same magnetic coil to generate the impeller and is self-propelling. So, you won’t be bothered by the manual spinning of water. However, these things are generally not suited for the canister filters as they offer less protection against moisture or debris, making them less protective and high maintenance.
The Valves
Here comes another important consideration, i.e., the valves. Generally, the canister filters come with 2 valves that are set there to control the intake of water and the followed output. Here, what you can do to ensure a quality experience is to look for valves that are completely closed so that the water stays in the hoses. Thus, having these at hand, you can disassemble your machine ideally for cleaning and maintenance.
Another thing here to consider is the connection between these two valves. Here, you should look for a feature such as a gravel vacuum or an adapter that can help you in disconnecting the valves from each other. So, you can conveniently eliminate the water, maintain, and re-prime the filter without any need to fill the buckets again and again.
Filter Options (Media Trays)
Before making a buying decision, you should make sure that your canister filter can hold as much media as you require. Most commonly, you can find a space for two media trays; however, if you are not limited by budget, at least try to look for three trays capacity. The key ingredient of a quality canister filter is to have as many options as they can offers.
First of all, make sure that your filter has a mechanical tray that is set there to remove any dust and debris in solid form. Second is the biological filtration that offers you a healthy bacterium to fight against ammonia and nitrates. Likewise, the last one you should look for is the chemical filtration that overall improves the water formula and its related chemistry problems. Having these three media trays can provide you with a smooth experience all in all.
A Convenient Alternative
Similarly, while you are investing in a canister filter, it is highly important that you have a fast, convenient, and reliable one to begin with. Hence, the thing that users are most bothered about is the cleaning or maintenance process. Generally, a simple filter demands cleaning after every three things that are completely dependent on the overall load and size of your tank.
Additionally, for this purpose, you can go for a filter that can be easily shut down and disassemble. There are many contemporary models that come with a shutoff valve, with absolute ease and a trouble-free disconnecting process. For many cost-effective, affordable filters, you will most probably have to adjust their components which can be a bit of a problem. Hence, based on your individual needs and overall budget limit, you can choose the one you need.
Noiseless Operations
If you are someone who gets bothered by unnecessary noise quickly, it is significant for you to look for something that produces minimal noise. As the noise level can have a big impact on the overall enjoyment and experience, it is ideal for you to consider the equipment that provides you with low decibel ratings. Here, you should also consider the overall position of the filter and the tank, as it can largely impact the noise level a canister filer has.
Power-Consumption/ Pocket-Friendly Filters
Last but not least, it is of paramount importance that your canister filter is energy efficient and helps you in providing you relief from overwhelming electricity bills. Considering the device is going to run for the whole day, it is significant that you have something that consumes less than usual power and is equally powerful. However, you should not undermine the overall flow rate and filtration efficiency as it can impact the overall effectiveness of your apparatus.
These canister filters are a great way to conveniently maintain your water tanks, having a quality motor and low power consumption level. If you are someone interested in buying a quality filter for your aquarium, I would recommend you do the research beforehand and consider this buying guide. Wrapping up, based on your individual requirements and budget limits, you can choose rationally which one to buy.
