On the Subject of Aquariums

If there is magic on this planet, it is contained in water.

The module displays a 6×6 grid divided into blocks called “tanks”.

You have to “fill” the tanks with water up to a certain level or leave it empty.

The water level in each tank is one and the same across its full width.

The numbers outside the grid show the number of cells filled with water horizontally and vertically. Not all numbers are given.

All the tanks with water (in blue) and all the tanks with air (in white) must be toggled. Click on a square to cycle it between unfilled, water, and air.

If you wish to reset the puzzle, you may press the red button.

The module will disarm once all the appropriate cells have been filled in with either water or air.
