One more thing to keep in mind is when you run 24/7 you don't give the smaller particles time to settle out so they will tend to remain in suspension and in this case, the only way to remove them is by filtering. It is far more cost effective to turn the pump off for several hours and let these particles settle out so they can be vacuumed up. However, if you don't have an automatic vac, it may not be time effective to do it that way. It all comes down to how you want to manage your pool and the how much you want to pay for it.
