What Are Canister Filters?

Before I get down to serious business, let me give you a brief introduction as to what really are canister filters and what they are known for. If you already know what it is, feel free to skip this part and move on to the rest of the article. To begin with, canister filters are large filters basically used to filter water in large aquariums. They are widely knowns for their efficient and effective filtration of aquarium water without poisoning the tank water with toxins and harmful chemicals. Moreover, canister filters are super easy to set up and maintain.

Fluval 406 Canister Filter

Fluval has been known to produce some of the most excellent canister filters that people find very easy to use. These filters are large in size and have multiple contact points that help filter your fish aquarium in a matter of minutes. So, you can finally turn that cloudy smelly fish water into crystal clear healthy water. Fluval 406 canister filter is an external filter and is highly expensive. However, the price is not what you should worry about because it is absolutely worth it. Following are some of the most outstanding benefits of using the Fluval 406 canister filter.

1. Efficient Three-stage Filtration Process

The Fluval 406 canister filter undergoes a three-stage filtration process i.e. mechanical, biological, and chemical. This breakdown of the filtration process ensures complete filtration thus helping you promote a clean and healthy environment for your fish.

Stage 1: Mechanical Filtration removes largely visible waste materials that float on the surface of the water tank.

Stage 2: Biological Filtration helps convert toxic nitrogenous wastes such as nitrites and ammonia into nitrates.

Stage 3: Chemical Filtration removes the rest of the dissolved chemical impurities from fish wastes thereby turning the cloudy water crystal clear.

2. Ingenious Design

Another thing I absolutely love about this filter is that it has an ingenious design that helps shove more water towards the filter so that more water can be filtered in a lot less time. It has a unique bottom-to-top filtration design that takes up water at the inlet, passes it through the filtration media, and lets it out from the other end. However, the secret behind the efficient water flow into the filter is the hydraulic motor fitted inside the canister filter. It regulates the flow of water towards the filter inlet thus filtering out the maximum amount of water at a time.

3. Noise

Most people complain about the loud noises their filters make while filtering the aquarium. However, the Fluval 406 canister filter is surprisingly quiet for its size and efficiency. Apart from the dimmed sound of water flowing into the filter, you will not hear a thing. Besides, the sound of water flow is pleasant to the ears. Anyways, you don’t need not worry about anything at all.

4. Quality

All things aside, what good is anything if it is made cheaply? But you need not worry about that either because the Fluval 406 canister filter is made of high-quality materials. The filter is highly durable and long-lasting. Not to mention, it is highly efficient and takes up only a small amount of electricity. So, you can rest assured that the installation of this canister filter will not spike your electricity bill too much.
