What is the Bubble Magus Curve 7 Protein Skimmer?

The Bubble Magus BM-Curve 7 Protein Skimmer is exactly what it says it is. It is a pumping machine that is used in aquariums to eliminate and remove organic wastes, like leftover food and animals discards, from the water. The main focus is to suppress the level of nitrate in reef aquariums which is known to hinder proper growth and interrupt the ecosystem inside. So what the Bubble Magus BM-Curve 7 Protein Skimmer have on offer for you?

Design and Construction

Can we all please take a moment to appreciate how aesthetically beautiful this skimmer really is? You know it looks nothing like those generic, bulky and oddly boxy skimmers that we are all used to. The Bubble Magus BM-Curve 7 Protein Skimmer has a curvier body which not only complements the setup but also allows the foam to smoothly rise to your collection cup.

It measures 10 x 28 x 12 inches in dimensions and weighs around 12 pounds, You should need 10X11 section in your sump for a comfortable fit.


Now, let’s get to the primary focus of the whole machine. First of all, the Bubble Magus BM-Curve 7 features a needle wheel pump (SPI1000) with a venture intake that produces air bubble not too big, nor too small. This keeps the pressure and oxygen level in check, which is obviously a big concern. One neat detail, by the way, which we bet most don’t know is the pump is replaceable! Anyway, to reduce turbulence in the reaction chamber of the skimmer, you have a bubble plate.

Cleaning Aspects


Next, and most importantly, you have your collection cup, which is easily removable and fairly sized, and the skimmer body for carrying the entire cleaning process. With the collection cup, you will find a drain which is there to eliminate you having to check up and clean the collection cup too frequently.

Quiet Operation

Lastly, and probably our most favorite feature on the Bubble Magus BM-Curve 7 is its air silencer which cuts down on the noise output significantly for a quieter, more relaxed operation.


Last but not least, you have the capacity factor. The Bubble Magus BM-Curve 7 is more than enough for a medium to large size aquarium. It can tank up to a whopping 240 gallons making it great for 150 to 180 galloner tanks. For larger than 200 gallon tanks we recommend Bubble Magus Curve 9.


  • Well designed; installs easily
  • Aesthetically pleasing
  • Large capacity
  • Replaceable pump
  • Great performance
  • Easy to clean and maintain
  • Isn’t loud


  • Tends to work on and off
  • Air inlet too close to the lid; gets clogged easily

Frequently Asked Questions (FAQs)

What is up with the instruction manual of this thing? Now what? I’m stuck.

We know, we know. The instructions that come with the Curve 7 could have been written down by a 5 year old, but it isn’t the end of the world. There are plenty on instructions on assembly, installation and troubleshooting on YouTube take your hope there and put down that dreadful manual.

Can I use the Curve 7 in a 130 to 150 gallons?

Well, we don’t see why you can’t. But it’s like having a horse do a donkey’s job, you know? Why use a pump this powerful when you have one that’s perfect for your aquarium. The Curve 7 has a predecessor the Bubble Magus Curve 5 which can handle up to 140 gallons. Try that.

Okay I know I could replace the pump of the Curve 7 skimmer, but how?

There’s a small red plug on the bottom of the skimmer. You just pull out the plug, take out the factory pump, insert the new pump of your choice and then attach the red plug back onto its place. Voila! Easy and straightforward.

I am having some trouble with the noise from the machine? How reliable is the customer service?

The customer service, we are glad you asked, is pretty reliable, actually. They do okay. But if you are looking forward to get some help with the noise issue then you just may not be pleased since the company does not cover that particular area as far as we’ve found out. You could still ask for try and ask nonetheless. No harm trying.
