Everyone has been so helpful here and I have tried figuring out my "head" etc, but I always get confused. My pump is a hayward super pump 1 hp, the filter is a 24" sand, the pool is a 15x30 gunite rectangle approx 18500 gal and my clean pressure is 11.5...so how the heck do i figure out the approx gal turnover? I read 1 turnover per day should suffice, but I am unsure in how many hours my pool accomplishes this task, so I have usually run the pump about 10 hours a day, usually this works???(totally guessing on that one)
Oh yeah...1.5 inch piping.
thanks for any feedback...still learning
