Replace the ball valve with a gate. If you are seeing that much fluctuation I am assuming that it is due to the rising and falling level in the overflow caused by the inaccurate adjustment of the ball valve. Either that or you are having some serious evaporation happening. Gate valves are minutely adjustable and allow for the fine tuning required to maintain the proper water level in the overflow.
