Tank Size Reality Check
Help beginners slow down before choosing a tank that is too small, too heavy, or too cramped for the intended livestock.
A planted aquarium is not only a glass box. It is water weight, hardscape, equipment, maintenance access, and animal space.
Use this check before buying a tank, stand, or livestock. It favors conservative planning because small tanks and weak furniture leave little room for error.

How to use this tool
- Enter the tank volume and rough footprint.
- Choose the stand confidence, room access, and stocking ambition.
- Read the weight and caution result before treating a tank size as settled.
What the result means
The result estimates filled system weight and names the main planning caution.
It is not structural advice, an engineering approval, or a species-specific stocking rule.
Assumptions and limitations
Filled weight is estimated from water plus a rough allowance for glass, substrate, hardscape, and equipment.
Species needs, local rules, stand ratings, and floor conditions must be checked separately.
