Top 5 Saltwater Aquarium Filtrations

Have you ever thought about having a fish as a pet? A lot of people assume that they are comfortable and low maintenance. All you need to do is feed them a few times a day and make sure that their aquarium is clean. It seems like it’s easy? Well, for the most part, keeping the aquarium clean is easy work but not if you don’t have the right filtration system.

Are you not sure what type of filtration system would best suit your aquarium? Choosing the right filtration system will make a big difference when it comes to how much time you will have cleaning your tank. When shopping around you want to make sure you are getting the right filtration system for your tank. How about we take a look at the five best filtrations systems for your aquarium!

Filter Reactors

Filter reactors are designed to improve water quality in your aquarium. There are different types of reactors, but the most popular model is PhosBan. PhosBan helps to absorb and remove phosphates and other pollutants. Other forms of filter media are bio pellets, GFO, and carbon.

Bio pellets are tiny pellets used as a filter in a media reactor. These small pellets are designed to improve water quality by enhancing the nitrification process. The process removes nitrate and phosphates from the water.

Granular ferric oxide or GFO filter media is used to remove phosphates and silicates. In saltwater tanks, GFO helps to reduce algae and growth of hard corals. Another advantage of GFO media is that it won’t affect the water pH.

Activated carbon is one of the most used filters in aquariums. Carbon filters are made for water purification, toxin removal, and other waste particles.

Canister Filters

Canister filters are mostly for saltwater tanks with plants. One reason for this is that this type of filter is more powerful and handles higher demands. Instead of being inside the aquarium, it is outside and uses hoses that connect to the tank intake and outlet. Canister filters are a 3-stage type of filter media. The 3-stage models would have the biological, mechanical, and chemical filter media. Because of its complexity makeup, cleaning can be a bit challenging for this filter. Nevertheless, washing must be frequent to get the best result. For a bigger tank, expect to get a more expensive canister filter to keep your aquarium clean all the time.

Refugium & Sumps

A Refugium is a smaller tank placed in the aquarium. This smaller container can be used for different purposes, yet it plays a crucial role for other aquatic species. A Refugium can be used to separate delicate species from larger fish. Also, Refugium is used to grow algae that will help break down or absorb waste. But for saltwater aquariums, Refugium is used to filter water from the main tank.

A refugium can be categorized into three types: sump based, in-tank, and hang-on. Each is designed for a specific purpose. Know which your need is before you go ahead and purchase one. Sump based Refugium is a second tank you placed in the main tank. If you incorporate a sump pump and a protein skimmer, this would be the most expensive of the three. The in-tank Refugium is the simplest of the three. It is a small container that is placed in the aquarium. Because of its size, it takes up little space and serves its purpose by keeping the more abundant species out and smaller ones inside. With it, you can see your delicate species grow. Hang-on tanks are just as what the name says. It hangs on to the back of the tank while sharing the water. This type usually needs a pump to move water in and out.

Protein Skimmers

Protein skimmers use many of the natural processes found in nature to remove DOC’s (Dissolved Organic Compounds) from the saltwater aquarium. One can easily see a protein skimming action in its natural state at the beach. As the waves crash, the edge of the water becomes full of “sea foam.” If you look carefully, you will notice that this foam is often discolored with what looks like dirt. It is, in effect, skimming the ocean waves and cleaning the water. The resultant waste products often wash up on shore. A protein skimmer performs the same primary process. It uses air bubbles, like sea foam, to both clean and intensely aerates the aquarium’s water.

Protein skimmers typically are in the shape of a round cylinder. It has a large body with smaller inlets and outlets. On top of the skimmer is a collection device or cup-like component where the waste collects. These cups can collect particulates which later end to be emptied, or they can utilize a runoff hose thus making the time between cup changes much longer.

Regarding the specific manner in which a skimmer works the air is forced into the impeller of a pump causing a highly oxygenated mixture of water and air. As the water is pushed through the chambers, the air struggles to rise to the top in the form of bubbles or foam while the water sinks and is returned to the tank. This mixture of air and water is controlled by adjustment valves that either allow more or less water into the mix. One must be careful not to let too much water into the mix as this has the potential to overflow the skimmer resulting in potential flooding. Put follow the directions supplied with the skimmer carefully!

One might ask why this is used instead of a conventional filter. Oxygenated water is far healthier for the marine inhabitants of the tank. The result tends to be a cleaner crystal clear tank that is both enjoyable to the marine inhabitants and to us humans who love to watch the fish.

There are many choices of skimmers available to the enthusiast. It is essential to know the environment in which the fish or marine inhabitants will live. Certain species prefer more oxygenated water while others prefer dirtier water. No matter what the choice there is a protein skimmer that will undoubtedly work for your tank.


Eshopps has a series of overflow boxes designed to fit any aquarium size. An overflow box transport water to a sump, Refugium, and wet/dry filters that are likely concealed in a cabinet. Overflow boxes can be placed in the aquarium or outside. Most often, they are outside between the tank and the wall. It helps with maximizing the space in the aquarium. All boxes are fitted with accessories to attach to the aquarium. They are easily installed and can be move if necessary. Eshopps carry a series of PF overflow boxes. The lower the series number, the smaller the quantity of water gets transported. The PF series include PF-Nano, PF-300, PT-800, PF-1000, PT-1200, and PF-1800. Another set of overflow box Eshopps has is Eclipse. Eclipse comes in small, medium, and large. They range from tank usage starting from 75-150 gallons respectively. Whichever choice you make, they are reliable, and with noise reduction, you would not realize you have one installed.

I know it is a lot of information thus far but remember filtration is very crucial and its importance cannot be brushed off. The fact of the matter is that the higher the level filtration in the fish tank the better it is for the fish. It is recommended that you always have a level of filtration that is way higher than the size of your fish tank. It means that if your fish tank says 50 gals, then you need a larger filter of up to 100 gals or even more or chooses to have more than one filter of 50 gals.

With all the different models out in the market, you are likely to get confused before you can settle on the best fish tank filter. Please make sure you pay attention to the quality of the filters longevity. The filter should be able to do you an impressive job with less of the letdowns. Any of these top fish tank filters are going to help keep your aquarium clean, healthier for the aquatic life support and easy to maintain in the long run.

I Hope these suggestions I have shown you help make you feel more prepared and excited for in your journey of being an aquarium owner.
