For example, a minimum wage of $10 per hour will have no effect for workers whose marginal productivity in a given line of work is greater than $10 per hour. The legal supply and demand remains unchanged for such labor.
One way to keep control of the time you run the swimming pool pump is to run it several times a day for short periods of time. If you want to activate the pump once a day, start with six hours, but never go lower than five hours, especially in the summer. If your pool is in constant use, you may need to run the pump for up to eight hours per day, frequently checking the water clarity and chemical balance.
The operation time will depend on the size of your pump and the size of your pool. The key to creating an effective and energy-saving run cycle is determining how long the pump needs to run in order to cycle all of the water in your pool. A rule of thumb for energy savings is to let the pump run for six to eight hours.
