Firstly, let me tell you why filters are necessary for your fish tank? You don’t want your beloved fishes to die from dirty water. Right?  Fish breathe in water. We all know that. But how are fishes going to survive when the water is not cleaned and filtered? The only thing that keeps fish alive is water. 

By using filters in your fish tanks, the water will be cleaned and filtered by removing the debris, dirt, and toxins from it. These toxins and dirt are harmful to fishes because they breathe in water.

 Overview 

Given the huge number of brands in the market, finding a filter that will best serve your purpose and tank size can be somewhat overwhelming especially if you are inexperienced in fishkeeping. Luckily, you don’t have to look further. With a product like the Marineland Emperor 400 Canister Filter, you can bring your worries to rest.

Loaded with tons of media capacity, this unit is a great choice if you’ve got a tank that’s fairly heavily stocked. It boasts of high processing power and a large cartridge capacity which not only gets the job done but puts it ahead of many similar models.

While this might not be the biggest or fanciest unit out there, it definitely brings a lot to the table to get the job done. The purpose of this article is to take an in-depth look at the product to help you determine if it’s a filter that’s really worth your money.

 Features and Benefits 

Let’s take a closer look at the facts and figures of this Marineland filter so we can see all that it really offers.

 High Processing Power 

One of the first things you will notice about the Marineland 400 when purchasing it for the first time is its high power. Unlike many conventional standard aquarium filters, this one is big and meant to be specifically designed for big applications.

To be more exact, this unit is built to handle aquariums that have up to 80-gallon capacity. So if you have a large tank that needs to be brought back to life, then the Emperor 400 is your brand.

Despite expectations, this machine still boasts a high processing power of 400 gallons of water per hour.

This simply means that if you have an aquarium that is 50-gallons in size, this filtration system will process the total water volume in the tank 8 times every single hour. You don’t find many filters in the market with such power, not even the most expensive ones. That means you get more bang for your buck with this filter. 

That said, we must point out that this unit is a bit loud. So apart from taking up some considerable space “outside the aquarium”, it might be a bit noisy. And given its high processing power, it will require a bit of energy too. Notwithstanding, all this is nothing compared to the great value you get for your money. More so, it shouldn’t come as a surprise considering the enormous work the machine does.

 Huge Filter Cartridge Capacity 

The Emperor 400 filter also boasts of a large filter cartridge capacity, which can be extremely useful if you have a tank that is fairly stocked.

While most canister filters can only boast of being able to handle only one cartridge, this unit can support twice the amount. This is why the machine is suitable for removing debris and chemicals, especially in big applications.

The cartridges used in the filter are usually those that serve for chemical and mechanical filtration. These cartridges are quite durable and very easy to replace. They also contain good quality filter media that gets the job done.

Interestingly, this unit also features an extra chemical and mechanical capacity, which gives you the option to purchase more media. Biological filtration is also taken care of by an efficient spray-driven bio-wheel to remove ammonia and other harmful chemicals.

All this ensures that the filter delivers clean and clear water, much to the delight of your fish.

It is important to note that bio-wheel requires frequent cleaning to maintain its efficiency. It’s also essential for the mechanical filter to always be in good working condition to prevent the wheel from getting stuck.

 Solid-Body Construction 

The most basic indication that a system will last lies in the kind of material used for body construction. Without a solid casing, there’s no guarantee you won’t replace your canister filter after a few months of use.

Luckily, you don’t have anything to worry about durability when you are using the Emperor 400 Pro Series bio-wheel power filter because it comes with a solid body construction that ensures it lasts you for a good number of years. It is not every day you come across a filter with such a reliable casing in the market.

Although the impeller and motor might not be as strong as the outside, this doesn’t change the fact that they still get the job done. So don’t hesitate to make the move if you feel the unit will serve your aquarium size and purpose.

 Hang-On-Back 

It is also important to mention the hang-on-back feature of this device because not many models have such a design. The reason why a hang-on-back is laudable for any canister filter is that it is space-saving for your aquarium environment. In our opinion, it also makes the aquarium more aesthetically pleasing because your view is not blocked by the filter. Instead, you can enjoy the view of your fish swimming about better.

Some filters usually need to be installed inside the water tank thereby taking useful space meant for your little buddies. No matter how powerful such filters are, they usually work best for fish tanks that are lightly stocked. Thankfully, this Marineland filter comes with a hang-on-back which means it’s meant to be hung at the back of your aquarium. So no space is taken inside the tank, which means more space for your fish and plants.

However, it’s worth mentioning this unit is fairly large so you will need a bit of clearance to hang on the rear of your aquarium. Usually, you will need about 5 inches of depth and 12 inches of width.

Once you get the clearance, just go ahead and hang the filter right behind your tank. Then secure it with the appropriate equipment provided, and you are good to go.
