Here's some info from one of the posts in the pool equipment section:

Most pools require 1 to 2 turnovers per day. What is turnover?

Turnover is the time it takes for the volume of the pool to run through the pump once. However, this does not mean that all of the water has gone through the pump. Some water goes through once, some twice and some not at all. To determine turnover rate:

First, determine the head loss for your plumbing. It is usually between 45-65 feet of head. If you want a better estimate, take your filter PSI and multiply this by 2.31. If you do not have a vacuum gauge, add about 10' of head for suction head. Otherwise, multiple the vacuum (in. mg.) by 1.13 to get suction head. Add return head and suction head to get total head.

Second, look up the the flow rate from the pump head curve that is usually in the manual. The vertical axis is head loss and the horizontal axis is GPM.

Third, use the formula turnover (hrs) = Pool Volume (gallons) / (gpm * 60)

Yes, it is usually a good idea to split the filtering time into two parts evenly distributed within a 24 hr period.
