Significant Capabilities You Should Consider

The reservoir you desire to obtain should solve your tank problems, either current or future predicaments. Here, we will share some knowledge about the standard capabilities you should consider before buying a reservoir strainer. 

Filter Type

If you are looking for a perfect drainer for you, you might get confused since there are many options to pick out there. Here, we will tell you some categories of waste filters you might consider before buying yours. Here are they: 

  1. Power/ HOB Filters – This type of strainer is also known as HOB(hang on back) Filters. These are most common, as they are relatively inexpensive. Also, it will give you the freedom to customize and select what medium you will use. However, it can be loud or noisy and needs some fair amount to maintain. 

Power/ HOB Filter Pros -It provides a remarkable three-stage straining process to your water tank. Assembling, it is simple, and maintaining it is relatively easy. What is more interesting about this strainer’s feature is it hangs outside of your reservoir. Thus, it gives more space in your tank if you want to add some decorations or some other fish. 

The majority of these kinds of filters have a flexible water movement rate. It is to give you the freedom to set-up precisely the needed water movement rate of your aquarium. Plus, some types of waste strainers can work for both saltwater and freshwater reservoirs.

Power/ HOB Filter Cons – Whenever you remove the cartridges, you remove the useful bacteria colony. It will again need time to grow to help your reservoir. Create a healthy environment. Since the Power/ HOB Filters have several cleaning steps, it needs a bit more maintenance than other types of tank filters(for instance, the sponge type waste strainers). 

Aside from those mentioned things, the number one complaint about this type of tank filter is the noise it produces.

  1. Canister Filters – This type of drainer is an efficient and excellent pick if you have a giant reservoir. It provides a superior straining process. However, these products are a bit larger and expensive compared to others. 

Canister Filter Pros – This type of filter provides a high-end biological, chemical, and mechanical straining process. The Canister Filters gives a superior straining process because the majority of Canister products are pressurized. It means that excellent materials will scan the liquid, which has undergone the straining process.

These excellent materials will help to trap small particles. It helps to enhance the liquid’s overall quality and the health of the fish in your tank. Canister Filters often open for adjustment set-up, for instance, accessories like gravel strainer, spray bar, or ultraviolet sterilizers.

Canister Filter Cons – Since Canister Filters are much bigger than other types of waste strainers, they take too much space in your reservoir. And therefore have a higher payment rate.

  1. Internal Filters – Internal aquarium filters are typically used in tanks with 20-Gal capacity or less. This type of internal filter has suction cups to mount them inside the container. It is excellent for people who want to make their tank flatted against their walls.

These filters are usually placed on the below part of the tank. It is because it intakes the impurities while helping to prevent debris from combining up or building upon the deepest part of your tank. For some reason that your current filter can’t reach, usually at the deepest part (also known as the “dead spot”), this type of internal filter is just an excellent worker to do the job, bringing water circulation to that spot.

Internal Filter Pros – If you have done some research, you will realize that most aquarium filters have great prices. These internal filters are ideal for medium to small size reservoirs with small to medium numbers of fish. One more good thing about this internal strainer is some versions of these waste strainers utilize lines. These two are responsible for assisting in producing oxygenating bubbles.

Internal Filter Cons – Internal filters are commonly recommended for fish-keepers with small tanks (unless there is a dead-spot in your container). So if your huge tank has much fish in it, you will need to get a larger filter.

  1. Sponge Filters – These sponge filters are types of waste strainers that are easy to use. It provides a biological and mechanical straining process. It is cheap compared to other brands available in the market. However, it can look bulky in your tank. Also, if you will use this type of filter, it needs a kind of air pump.

Sponge Filter Pros – This sponge filter is relatively cheap and super simple to install. The most distinguished function of this drainer type is that it allows useful bacteria to create a colony. It means it is excellent for the mechanical straining process; the reservoir is getting a tremendous biological straining process!

Sponge Filter Cons – Sponge filters may look huge and bulky inside your tank. Some of its air pumps might be a bit noisy, too. The majority of sponge filters are recommended for the reservoir to 10-Gal in size, which means it is limiting the option for bigger tanks.

However, there is still a solution available. If you place several sponge filters in one specific tank, it might give sufficient straining process rates. Also, some of these filters can be combined and function well with Power/ HOB Filter.

  1. Under-gravel Filters – From the name itself, it is usually placed at the lowest part of the tank. It sucks the debris and water through its gravel. The function of this drainer is to trap the trash in the gravel while doing the straining process. After that, the liquid with debris-free will go up through the attached tubes. There is an air stone in it. This air stone is being inserted on the upper part of these tubes, so it creates a suction effect. 

Under-gravel Filter Pros – Aside from what already mentioned above, these types of filters are ideal for building a colony of useful bacteria. Plus, small fishes are safe because of its reliable air pump and air stone.

Under-gravel Filter Cons – If you use this kind of filter, you may soon realize you need an additional chemical and mechanical straining process, especially if your tank is a bit large. It can be the source of building high-level hydrogen sulfide, a chemical that can harm your marine animal friends. Since some need the help of the air pump, it will increase the noise level inside your tank that may disturb your marine animals. 

Note that there are still many kinds of filters out there in the market, but these five are the most common strainer you will encounter when buying Best Fish Tank Filters for your tank. After you read this section, you can now start fishing your reservoir tools for your marine animals.

Media 

Filtration media are responsible for maintaining your tank in a healthy condition. It has various substances. Mostly it comes with a type of media cartridge. This type of media can provide biological, mechanical, or chemical straining processes or a mix of two or three of them. You also must note that most reservoir or tank filters will give you that freedom to choose or add your media.

The Three Types of Filtration System:

  1. Mechanical Filtration – The mechanical straining process’s responsibility is to trap the dirt and debris floating around your tank’s liquid or hydrophobic materials. These hydrophobic materials are accountable for polluting your reservoir. The strainer floss or sponge you place inside your container that does the job. In other words, the mechanical straining process gets rid of solid wastes.
  2. Chemical Filtration – When you enter an activated carbon inside your straining process system, you hope it eliminates the reservoir’s odor or discoloration. The one causing the terrible smell or and stain are organic wastes, and that is where the chemical straining process will come in to help. 
  3. The Biological Filtration – The toxins such as ammonia and nitrate are the results of this nitrogen cycle. These toxins are harmful to your little marine animals. The biological straining process will eliminate these toxins from your tank for you. These toxins are called organic wastes. 

Run Rate

The logic of the run rate is simple. If you have a giant reservoir, you need a higher rate from the strainer you will use. The measurement used to count the liquid movement rate is a gallon per hour and the volume of liquid that the straining process stuff can filter in one hour. You must choose the reservoir filter that aligns with the rate and the size of your reservoir.

Noise Levels

Unfortunately, there is a noisy aquarium filter available in the market. This noise concern will not be a problem if your marine animals are located in a place where you do not need to frequent often. However, it might be so irritating if the reservoir is located in your primary living room or bedroom.

With that said, some updated filters are manufactured to be super quiet if it is not silent. It makes sense why people who love nature, especially fishing, consider this capability before buying a strainer.

The smartest strategy to spot the best fish reservoir strainer for noise level is to observe their advertisement. If their selling point is a low volume in their ad, then it is a bit obvious they got one of the best fish reservoir strainer silent or quiet waste strainer in the market.

Frequently Asked Questions About The Best Fish Filter/Pump Products; A Filter Review

It would be best to check this section, especially if you are a beginner in this industry. This FAQ will stand as your buying guide in the future. If you wish you could know all about tools and accessories in this industry, well, now is the time to start.

What is an aquarium filter, and how does it work?

The name answered it, itself. The filter is a kind of equipment that aims to get rid of dirty materials and chemicals that can be harmful to your marine animals and the health of your tank. Another goal of the waste strainer is to create oxygenation with excellent effectiveness for your fish to “breathe.”

The wastes strainer available in the market is slightly different from each other. However, the general feature of these filters is the tube that vacuums the dirty waters in. Then it pushes through the straining process stuff or media inside.

The media will trap the dirt and eliminate impurities. So the liquid will be fresh and clean. The new and clean water will return to your tank via a separate tube or a kind of waterfall-style system.

What size of the best fish tank filter do I need?

You must know by now that selecting the correct filter’s size for your reservoir is important. It is because of the liquid movement rate. The larger your tank, the larger the fluid movement rate you will need in your straining process stuff. 

The majority of best fish tank filters in the market mentioned what reservoir size is suitable for them. However, the general adaptation is that the rate (in hourly set-up), should be four or three times the total amount/capacity of your tank.

Do I need an air suck if I have a filter?

The majority of best fish tank filters do not need an air blow as long as there is a feature that the strainer is oxygenating. However, you still need to check its product description if it requires this feature to function, like the sponge type trainers.

Can a fish survive without a filter?

In theory, fishes could hardly survive or cope-up without filters. Without filters (responsible for maintaining the healthy environment of the tank), the fish’s life might decrease, and the fish’s lifespan might be shortened. Also, some fishes that are sensitive, selective about their home conditions, and may not survive.
