The Fluval 06 range of external filters sit outside of the tank, which means that they do not take up valuable water space. They come in four sizes to suit different sized tanks:
The 106 model, for tanks of up to 25 gallons
The 206 model, for tanks of up to 45 gallons
The 306 model, for tanks of up to 70 gallons
The 406 model, for tanks of up to 100 gallons
The range of filters is more expensive than some other options and also more expensive than Fluval’s own internal filters. However, if you want to invest in good quality kit that will last a long time, the 06 range is highly recommended.
All of the products in the range come with a three year manufacturers guarantee.
How do Fluvial 06 Series filters work?
The Fluval 06 range of filters provide multi-stage water filtration within a sealed unit that sits outside the tank. The filter draws water up into itself before returning the filtered water back into the tank.
The impeller unit is protected by sound dampening, making it one of the quieter external filters available, and it has a clog-proof strainer and two layers of foam screening.
It benefits from an aqua-stop valve to prevent run-back, and contains multiple different levels of filtration baskets that can all be easily accessed to clean and change the filter material.
Are they effective?
The mechanical, chemical and biological stages of filtration all run separately within the single unit, optimizing the available space and providing highly effective filtration.
Cleaning the unit is easy and not particularly messy, and you can use the unit with the provided media or filter media of your own choosing if you prefer.
The motor is powerful but quiet. Providing that you pick the right size filter and the right spot for the intake and output tubes in the tank, these filters will cover all of your tank’s filtration needs without taking up space in the water.
It is also particularly easy to set up the filters in the 06 series, making them an excellent choice for beginners.
Are there any downsides to choosing a Fluvial 06 Series filter?
While the 06 range is at the top end of the market for goldfish tank filters and is significantly quieter than most other external filters, it does still produce a noticeable hum.
You should consider where the filter will be placed. Like all external filters, it sits outside the tank and doesn’t look particularly attractive! Of course, if you have an aquarium cabinet then you will be able to hide the filter unit out of the way.
