Could a Juwel Trigon Aquarium Be Unstable?

Good question. The Juwel Trigon aquarium has a safety base frame that distributes weight evenly making it virtually impossible to tip or tilt. The sturdy cabinet this aquarium sits upon can hold up to 1.3 tonnes safely.

The impressive fifty-gallon tank will get pretty heavy when filled, which actually helps keep the trigon stable when sitting on its cabinet base.

Speaking of the cabinet base, it is not only very attractive but also very useful. It’s a great place to store all your fish accessories and equipment.

What Else Makes Them Special?

Ok, so we know they’re triangular shaped and that’s way cool, but what else makes the Juwel Trigon special. One simple yet important fact is it’s made by Juwel, meaning excellent build quality and a 2 year guarantee.

Juwel is a well-supported and highly trusted brand all over the world. They create many of the products needed for their aquariums (which come in a variety of styles and types) such as their own lighting, filtration, accessories, and more.

Juwel Trigon Aquarium Lighting

Juwel creates lighting tubes, units, systems, reflectors and end caps. Their T5 Hi-Lite lighting tubes (used in the Trigon) create astonishing colour inside your tank with spectrums that bring out the rainbow of colors in your aquarium.

The colours you have to choose from doing more than just highlight specific hues, however. For example, Hi-Light Nature has a green spectrum that promotes plant photosynthesis while highlighting green tones.

The Trigon comes with a BioFlow 3.0 filter system and heater. The BioFlow filter comes with five high-quality filter media and a powerful yet quiet pump.

The heater is either 200 or 300 watts (depending on 190 or 350 aquarium) and is part of the BioFlow filter system.


You’ll find the Juwel name on many accessories including automatic feeders, digital thermometers, heaters, filter media and much more.

Now that you’re convinced on how special Juwel aquariums truly are, you are probably even more excited about the Juwel Trigon 190 or 350. You are probably thinking along the lines of:

Where can I buy one?

You can find a list of dealers who sell Juwel aquariums in your area by visiting Juwel Aquariums.co.uk, or for your online shopping experience - you can also purchase them from Ebay.co.uk 

The trigon 350 retails on Ebay for around £ 1100. For an aquarium with the reputation and quality of Juwel, this is an amazing price for a 50-gallon aquarium.

The Juwel Trigon is more than an aquarium. It is a decorative addition to any room, a great conversation piece and an impressive corner fish tank .

Marine and saltwater tanks come with a learning curve if you have never owned one - but that battle is short lived, with the pleasure, and enjoyment that your Juwel Trigon aquarium will bring you for many years to come.
