I've been trying to figure out how long to run the pump for and just want to make sure I'm not doing this wrong.
I have a 1.5 hp pump and a 20x40 33000 gal pool.
I'm thinking in the range of 8 to 10 hours.
Also does it matter time of day? Obviously electricity is cheaper at night...
And does it matter if the returns are pointed down? ( That's what the crooks over at chemex tell me, to point them down as much as possible)
