The short answer
For anything beyond a tiny nano tank, yes — you need a proper stand. A full aquarium is enormously heavy for its size (about a kilo per litre plus glass), and that weight must sit on something rated, flat and dead level. A stand isn’t an optional accessory; it’s a safety-critical part of the setup.
Why a stand, not just any table
A stand built for aquariums is designed to carry the concentrated load and to keep the base perfectly flat. That flatness matters as much as strength: any high or low spot, or a stand that isn’t level, puts uneven stress on the glass and its silicone seams — the classic cause of a leak or a burst tank. Ordinary furniture rarely offers both the strength and the flatness a tank needs.
When you might skip a dedicated stand
Very small tanks — a 20–30 L nano — can sit on solid, level, water-resistant furniture that genuinely takes the weight, ideally on the tank’s foam base mat. See can I put an aquarium on a desk. But the larger the tank, the more a purpose-built stand becomes essential.
Setting up safely
Confirm the floor can bear the load, place the stand where the tank will stay (it can’t move once filled), check it’s level, then build. See where to put an aquarium and how to set up an aquarium. Browse tanks and kits on the aquariums hub.
