Best for heavy bioload: Bubble Magus QQ1 Hang-On Nano Protein Skimmer


We are starting the review with a nano yet powerful protein skimmer for the 20-gallon water tank. This is a hang-on skimmer introduced in the market by bubble magus. 

This product is generated for use in an aquarium that is heavily loaded. A closer look at the features will give readers a proper idea.


This is a small size protein skimmer. So, it fits easily in smaller tanks. It is innovative to use for tanks up to 25 gallons. 

A rock SP600 pump is there to offer maximum power and smaller bubbles to filtrate the water without causing any trouble.


This product is easy to install and effortless to use. It takes day one or two to start working in a heavily loaded water tank. The needle wheel pump reduces the foam bubble of water and makes the water look cleaner.

There are some maintenance issues regarding this product. You need to clean the collection cup regularly. Also, the sponge needs to be rinsed regularly.

The features we like:

The filtration system and the power supply of this skimmer are quite extraordinary. A briefed detail is provided so that readers get a better idea.


This is a smaller size skimmer that works wonders. This compact tool produces a good amount of skimmer and leaves a healthy environment for your water pets. 

It is easy to install and works fine just after 2 hours of installation. The product is made of high-grade material and the quality is tested by professionals.


It provides adequate support for smaller tanks from 10 gallons to 25 gallons. It’s better not to use a 30- or 35-gallon water tank. 

There is a magnet that makes the product easier to tune. Also, it ensures great support for a good amount of time. Also, it is quite durable.

But the reservoir of the skimmer is pretty difficult to remove. Also, the skimmer sometimes overflows and creates quite trouble for the user.
