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.
I would think that for your size pool and pump your baseline is 2 x 4 hours. I would consider 3 x 2.5 hours too. From there you can work your way down or up as needed. The big thing is if you are playing with the filter times then you need to keep an eye on the pool.
