When it comes to aquariums, there are a lot of options to choose from. Sometimes the choices might become too muddling, and it is at that moment you have to decide which size of an aquarium you should buy.

Reef or marine tank aquariums can be costly to install and tough to maintain. However, nano reef tanks are inexpensive aquariums in which you can keep your favorite corals and fish.

Since the last decade, nano marine tanks have become popular. The best ones are pretty affordable, and you don’t need over the top components to maintain them.

Nano marine aquarium keepers know how relaxing it is to sit back and watch the corals and fish of various shapes and sizes. If you plan on buying a nano reef tank, there are some things that you should be aware of.

When you keep corals and fish in the tank, you’ll generally need to buy LED lights, a filter, a wavemaker, and a protein skimmer. Therefore, it is crucial to be prepared beforehand.

However, all these considerations come later after you purchase an aquarium. Thus, in this Fluval Evo 5 review, we will be discussing a quality nano reef tank, its different features, pros, and cons. Based on the article, you can decide if this product suits your needs.

Things to Consider Before Buying

Other than being economical, nano marine tanks can fit into small areas. You don’t need to clear an ample space to set it up. They are also flexible, so you can move them around to change your aquatic setting.

However, being small also has its disadvantages. You can’t grow or keep as many fishes or corals as you want. For instance, you can’t keep large and aggressive fish in your tank.

The small aquariums are also known to accumulate toxins and debris faster than large tanks. You also have to maintain the fluctuating temperatures of your tank.

·      Not Suitable for SPS Corals


The corals are divided into two categories, Large Polyp Stony and Small Polyp Stony. If you are a fan of Small Polyp Stony Corals, also known as SPS, then this product is not for you.

It has been observed that the SPS needs more care and attention than the LPS. This is because SPS is less tolerant of low water quality, and they also require high flow and light.

Furthermore, they also tend to overgrow, and they need a consistent supply of minerals like magnesium, calcium, and alkalinity. Therefore, they can’t survive in this Fluval Evo reef tank.

The output of LED given to this tank, as well as its water flow, will be insufficient to grow SPS. If, however, you still want a reef tank that can develop and maintain SPS, then you should opt for the Coralife Fish Tank.

It is a little bit larger than the Fluval Evo, and this helps to maintain the stability of the water parameters. So, you can successfully grow SPS corals in this aquarium.

The nano tank includes a casing, which makes it easier to view the corals and marine life.

·      Three Stage Filtration System

The three stages of filtration are biological, chemical, and mechanical media. This powerful system keeps the tank clean and healthy at all times and helps prevent diseases and illnesses of marine life.

Furthermore, the biological, chemical, and mechanical filter will effectively remove bacteria, chemicals, and debris from the marine tank. Unlike other aquariums, you don’t have to purchase the screen and light separately.

The filter system will not mar the beautiful design of the tank because it will always remain hidden in the honeycomb structure. Furthermore, the system is said to become silent after a few days. So you won’t be disturbed by any noise from the filter.
