Hello everyone, I would like to start a discussion on the topic of “How stable is the IKEA Kallax shelf when placing a fish tank on it?”
My question is specifically about whether the Kallax can reliably support the weight of a water-filled tank over extended periods without sustaining long-term damage or creating safety risks.
I understand that water is relatively heavy: 1 liter weighs about 1 kg (2.2 lbs), and a small to medium aquarium can quickly hold 50 to 100 liters (13 to 26 gallons) or more, which means 50–100 kg (110–220 lbs) of water weight alone, not including the tank itself and any equipment.
Does anyone have experience with this kind of load? How does the stability of the shelves and the quality of the materials hold up? Are there any special tips or reinforcements that should be applied?
I look forward to your answers and discussions!

I have already assembled the Kallax shelf; it is the standard 4x4 model (so 16 compartments). I wanted to place the aquarium in two of the lower compartments…That is good, as the larger surface area of the shelf panel can help support the load. However, the individual shelves in the Kallax unit are not designed to carry such heavy weights.
Therefore, I would recommend not only firmly securing the back panel (which is often just cardboard strips) but also reinforcing the side and bottom panels with small wooden braces or metal brackets.
It is also important that the surface under the aquarium is completely level and stable to prevent point loads that could cause deformation. The weight of the water acts as a static load, disregarding any movements or vibrations.
Have you already measured the thickness of the shelf panels? The original panels are about 12 mm (0.5 inches) thick, which is not ideal for continuous heavy loads.

The question "How stable is the Kallax with an aquarium?" is not only a technical issue but also something that affects us all. Especially since an aquarium holds emotional value and you rely on everything being safe.
It would be unfortunate if something were to happen despite all precautions. I once had a small damage to the shelf that I initially ignored – and unfortunately, it led to greater stress on the unit.
My advice is to play it safe, for example by adding extra reinforcement or a support base. Your investment and the well-being of the fish are worth it!

Good morning,
I would like to systematically address the problem here:
1. Material and Load Capacity: As mentioned before, the Kallax is made of MDF, which is not waterproof and swells when exposed to moisture. Prolonged exposure to water can significantly reduce its stability.
2. Load: A 60-liter (approximately 60 kg or 132 lbs) aquarium load (water plus its own weight) is relatively evenly distributed when the aquarium is placed on a suitable baseboard.
3. Recommendation – Reinforcements:
- Use a plywood board as a base (at least 18 mm (0.7 inches) thick).
- Stabilize the bottom of the Kallax with additional corner brackets or metal profiles.
- Secure the shelf compartment on the sides with metal brackets to prevent deformation.
4. Maintenance and Inspection: Regularly check for any deformation, signs of moisture, or damage.
In summary: Without additional reinforcements, long-term loading is critical. With the measures mentioned, the Kallax is suitable for a 60-liter aquarium.
If you like, I can create a simple diagram for this.

Kallax is not designed to support heavy aquariums.I agree with that.
It’s better to use dedicated aquarium stands – they are built to handle such loads and provide safety.
A brief summary from my perspective:
Kallax is stylish, affordable, and flexible, but water is heavy and doesn’t stay without pressure.
If you want to play it safe, install reinforcements and check regularly – that way you'll have more fun and fewer worries. 🙂
And always remember: your fish and plants depend on you! ;-)
