What is the Bubble Magus Protein Skimmer like?

Keeping fish in water without monitoring them is a sure way to subject them to stress and diseases that can eventually kill them.

However, this is exactly what protein skimmers do. A skimmer is a device that removes organic compounds to keep the water clean of food and fish waste.

In this Bubble Magus Protein Skimmer review, we’ll explain how this device works and how it can help you keep your aquarium in top condition.

The Bubble Magus Protein Skimmer is available in various versions that work to maintain the water quality in saltwater tanks.

Depending on the size of your aquarium, pick the appropriate protein skimmer:

Each one of them features an internal pump to remove the waste from the tank.

The device doesn’t feel bulky and is easy to set up and use. Smaller tanks would be better off with a nano protein skimmer.

Here are some of the stand-out features of many Bubble Magus Skimmers.

1. Needle Wheel

bubble magus curve 5 review

This is the Bubble Magus Curve 7 Skimmer and it’s one of the most popular models.

This protein skimmer features needles that aren’t really sharp but whisk the water at high speed to create bubbles.

The bubbles bring the contaminants and organic waste from the bottom of the tank to the top where it’s collected in the collection cup to keep the water clear.

2. Efficient And Quiet Operation

Keeping your aquarium waste-free is an easy job because the skimmer does the job on your behalf.

It collects all the waste in the collection cup, where it is later drained through the drain tube.

You won’t have to remove the waste manually, so keeping the tank clean will be a straightforward job.

Nevertheless, you have to clean the collection cup regularly as this will guarantee that the protein skimmer will do its job properly.

However, this is an easy task that doesn’t take much time.


The Curve 5 and Curve 7 models feature a strong SP1000 internal pump.

The larger Curve 9 features a stronger SP4000 internal pump.

This pump is more efficient if you’re trying to maintain a bigger aquarium.

One of the perks of owning this protein skimmer is that it works without much noise.

The silent operation won’t disturb your fish or anyone else in the room as you eliminate all the waste in the tank.

There’s a silencer attached to the pump to guarantee noise-free performance.

If you feel that the skimmer is producing too much noise, it’s time for maintenance. This means that the silencer might not be working correctly.

3. Easy Setup

These skimmers are made of high-quality parts, designed to withstand heavy-duty use.

They arrive with detailed instructions that allow you to assemble them properly.

There are graphs and pictures that you can refer to if you feel that you can’t put the pieces together.

However, the company doesn’t respond promptly to inquiries, which can be a problem if you have never set up a protein skimmer before.

Nevertheless, there are plenty of online forums, YouTube videos, and Facebook groups where you can find answers to your questions.


At the same, you can easily take the protein skimmer out of the water and clean the internal parts thoroughly to keep it functioning.

There are two screws at the bottom of the protein skimmer to remove it and clean the internal parts.

This feature comes in handy because the air inlet is very close to the lid, so it can get clogged easily, especially if you’re overfeeding your fish.

Nevertheless, you can quickly remove it and clean the internal parts to keep the protein skimmer in excellent condition.

4. Short Break-In Period

After you’ve installed the protein skimmer, you can see the froth collecting in the cup overnight.

Once you have put all the pieces together, the skimmer will start working instantly, so you can easily remove the contaminants from the water.

In some cases, you might not see immediate results. This could mean that some of the parts haven’t been properly assembled.

In this case, you need to remove the pieces and put them back together to keep the tank in excellent condition.

If you have put everything together, you might need to adjust the water level.

The water level adjuster has a good grip and can be used by dry or wet hands to adjust the water in small increments.

Although there’s a guide provided for the recommended water level, you can tamper with it a little to make sure that the protein skimmer is working the way it should.

This is also necessary if you’re dealing with overflow issues. The recommended water level is between 9.5 and 11 inches. A good osmolator and overflow will also help you stay on top of water levels.

Pros Of A Bubble Magus Protein Skimmer

This protein skimmer is an excellent tool to use when you’re trying to keep an eye on your aquarium.

It has several advantages:

  • Easy to set up and assemble – anyone can put this protein skimmer together, even if they have no previous experience with similar tools
  • Features a powerful pump with silent operation – it doesn’t cause much noise or disturbance while it collects the waste from your tank

Cons Of A Bubble Magus Protein Skimmer

Despite its amazing features, there are a few things that you need to take into consideration before buying this protein skimmer.

Disadvantages include:

  • Although it’s quite straightforward to put together, the company’s representatives don’t respond promptly if you have an issue with installation. You will have to look for answers on online forums where other people can help you with their previous experience.
  • Some tampering with the water level is needed to make sure that the protein skimmer is working the way it should. This is possible thanks to the water level adjuster.

  1. I’ve got one of the older models and it’s served me well. Just looking for an upgrade now. Wouldn’t go with another brand.
