i think about 220 would be a good amount
A good rule of thumb is to fill the bottle about one-third to one-half full with water before launching the rocket. This amount of water provides enough mass for propulsion, but not too much that it affects the rocket's flight. Experimenting with different water levels can help you find the perfect amount for your specific rocket design.
4.SEK = 43Cents for a can and ~20SEK for a 2liter bottle.
The mor the better

The mor the better
The mass of a rocket bottle depends on various factors such as the size of the bottle, the amount of water and air pressure used, and the desired altitude or distance that the rocket needs to achieve. Generally, a rocket bottle mass should be light enough to maximize its acceleration and height while still providing stability during launch.
Typically, you should fill a bottle rocket about one-third to halfway with water. The exact amount of water may vary depending on the size of the bottle and the desired launch height. Experimenting with different water levels can help you find the optimal amount for your bottle rocket.
Having the right amount of water in a bottle rocket is crucial for optimal performance. Too much water can make the rocket heavy and affect its height, while too little water can lead to a premature ejection of the compressed air, reducing thrust. It's recommended to find the right balance for the best launch.
If it is a commercially produced water/air rocket, follow the instructions exactly. They will tell you how much you need.If you made it yourself from a plastic bottle, you should perform a series of experiments to see how much water gives the best altitude.BTW, there is no fuel in these rockets. Water is the propellant that "pushes" on the rocket as it leaves the nozzle. Air pressure pushes the water out the nozzle.
