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.
Recommended minimum pump time in Filter mode is between 6 and 8 hours for both above- and in-ground pools, although if you plan to have a pool party with many extra users, you may want to run it for a full day before and about 48 hours afterward.
