To adjust the water tank of the Waterrower correctly, first ensure that the tank is filled to the appropriate level based on the desired resistance level. The water level can be adjusted by adding or removing water using the included siphon pump. For a higher resistance, fill the tank closer to the maximum level, and for a lower resistance, fill it closer to the minimum level. It's important to follow the manufacturer's guidelines for adjusting the water tank to ensure optimal performance and to avoid damaging the machine. **
