Things to consider before buying the best Nano Protein skimmer

If all of the eight models I discussed above are still not enough, what you want, then this part is exclusively for you. Here I will be talking about what you should check before buying the Nano protein skimmer. Just follow my footprints, you will find your desired skimmer.

Pump Types

Always remember, the more bubbles it creates, the more cleanliness you get. There are types of pumps in the market.

1. Venturi Pumps

You will see microbubbles while using the Venturi pump. Here, water runs under high pressure through an hourglass-type tube. Air gets mixed with the water and creates bubbles. The Bernoulli principle is applied in this technique.

2. Turbo Pump or Needle-Wheel

In turbo pumps, blades agitate the water to make bubbles.

3. Counter Current Pumps

It swirls the water with air and creates micro-bubbles.

Placement of The protein skimmer

1. In Sump

Super easy. These kinds should be installed in the aquarium sump. Then, there is nothing left to do.

2. External Model

There are external models in case you want to keep the nano skimmer separate. Water will be going using a pipe into the skimmer. The skimmer will draw back the water into the tank.

Different nano protein skimmers work in different methods, but you will find similarities in the cleaning process if you take a closer look.

Most importantly, it depends on your tank’s compatibility and your preferences.

Size Matters

Do not just buy a model for your aquarium. The size of your tank and the size of the skimmer should have compatibility. Otherwise, cleaning will go wrong, and you will get unwanted results.

If you are planning to have an external nano protein skimmer, then the story is different.

There are ranks in the size of skimmers. Check your tank size, find out the rank and buy the matching size for you.

Do not get Fooled by the Looks

A costly nano protein skimmer with a futuristic design does not give you the best service always. Do not fall for the looks. Judge it by its working process and capacity.

Talk to experts or people who are using these right now. Their experiences will make your decision more precise and perfect. After all, reviews of the users are genuine factors to judge any products.

Durability and Build Quality

People do not buy nano protein skimmers to change it after every few months or years. Keep this in your mind; it is your long-term investment. So, be careful about what you are spending your money on.

Damaged or malfunctioned products are strictly avoidable. Take a skilled person with you while buying a nano protein skimmer.

Easy Maintenance

Just imagine, it would be so easy if we could just forget about the nano protein skimmer after installing it. In reality, it is not going to happen. You have to take good care of it.

Some skimmers come with a waste collection cup. Some of them also come with collection cup drains. This drain takes the waste in a big container. These features minimize your maintenance efforts.

A nano protein skimmer without these features means you have to clean it on your own. Otherwise, it gets jammed and becomes smelly.

How to Set Up a Nano Protein Skimmer

You can find countless styles, sizes, and types of protein skimmers. Here we will discuss consecutively how to set up a nano skimmer without any unwanted incidents.

At first, while picking a protein skimmer, make sure that the capacity of the skimmer is bigger than your tank’s capacity. For example, if you have a tank which capacity is 20 gallons, try to find something not less than 25 gallons.

Secondly, while placing the protein skimmer, examine it thoroughly. Skimmers are available in a variety of shapes and sizes. In fact, they have a variety of parts. You need to be extra careful while unpacking, all the necessary components have been given, and none of them are missing. Also, make sure the engine works properly.

Then, you may have to assemble the skimmer. Nevertheless, most of the skimmers come in a pre-assembled format. However, in case you have to do it yourself, then check the manual instructions carefully.

Next, you need to find out whether you have a sump box or not for your aquariums’ water filtration system. If the answer is no, then put a sump box underneath the tank. You will find an output and intake hose, then have to connect it to the pump.

To get the best output, you have to monitor your skimmer for the first few hours. At the same time, you may need to reduce or raise the skimmer’s water level. Then, if necessary, reduce or increase the air measurement into the protein skimmer.

Ensure that the sump box properly distributes water from the tank to the sump box and back again. You may have to put your protein skimmer inside the sump box. However, some of the designs allow you to fit it outside of your aquarium. Finally, connect the skimmer with a power supply.

How do Nano protein skimmers work?

Protein skimmers are also known as foam fractionators. The core purpose of a Nano protein skimmer is to simply detach unwanted elements and pollutants by transporting them to the water surface and extracting them all through filtration. This is conducted by producing microbubbles.

The skimmer generates foam, which is small, sometimes microscopic air bubbles that float to the water surface in your aquarium. This foam gathers wastage and byproducts in your tank.

You may find it a little bit strange but let me help you out. All harmful particles have automatically adhered to the outside of the microbubbles.

In short, the protein skimmer involves removing pollutants and wastages from the water using a chemical process. Unwanted waste and degraded organic elements will stick to the surface of the protein skimmer’s air bubbles. The skimmer makes countless bubbles to pull them out of the water in your tank.

The rubbish from all these bubbles will be collected in a collection cup and taken away by the aquarium holder. This waste is known as skim-mate. Basically, the water gets cleansed continuously even if you operate a nano skimmer the whole day.

Why Use a Nano Protein Skimmer?

Skimmers filter out such unwanted organic material from your tank. As a result, they are formed once they disintegrate and create undue harm in your aquarium.

If you keep a variety of fish, a protein skimmer can help keep the water clean. Therefore, a protein skimmer can operate as a filtration system by producing bubbles that soak up wastages from the water’s surface.

Some saltwater aquarium collectors never use protein skimmers, and their tanks perform quite ok. However, having a protein skimmer greatly simplifies tank monitoring.

So, when the volume of water is limited, as in a Nano tank, it is conveniently contaminated, which could be a major issue for its inhabitants.

A protein skimmer creates bubbles in the water, whereby the decomposed substances attach to and float it away to the collection cup of the protein skimmer.

To purify the tank water, it is obvious that you need a protein skimmer. They do a great job of keeping your water clean, fresh by erasing excess organic ingredients and wastage. These components, if overlooked, can create a bad impact on water quality and cause unacceptable damage to the aquatic life in your tank.

Installing the best nano protein skimmer can assist you in resolving the whole difficulties and leave you headache-free.

How to Maintain a Nano Protein Skimmer?

You might be amazed at how fast and easily a protein skimmer becomes Messy. The collection cup should be emptied regularly, but the skimmer itself should be cleaned thoroughly even so often. This enhances the skimmers efficiency and durability

Usually, customers become conscious to maintain their aquarium’s environment clean and fresh without any disturbance. You may also find it irritating if your tank is being contaminated frequently. Therefore, there is no alternative without having any protein skimmer. Most companies are aware of the requirements for a Nano protein skimmer to fulfill their customer desire.

Maintenance is essential, as it is with all equipment. Calcium and other deposits should be removed from your pump frequently. You should also wash the skimmer body regularly to erase unwanted dirt, which has adhered to the sidewalls.

Finally, you will need to empty the collection cup on a routine basis. The regularity with which you must empty the collection cup is determined by how it is regulated.

Every six months, you need to cleanse your protein skimmer properly. The collection cup, on the other side, should be sanitized several times per week. If your tank does have a significant bio-load, cleaning it every day may be required.

The cleaning is however very simple. It generally entails washing the collection cup/waste container and ensuring that the equipment is in proper operating order.

What are the benefits of using a Nano protein skimmer?

Protein skimmers are a must-have item of aquarium filtration that almost every reefer has in their sump. It isn’t easy to accomplish without it, but monitoring the percentage of organic nutrients allows aquarium upkeep relatively simple and easy.
