Oh, now THAT is a COMPLETELY different question!

Lots of factors come into it. I have solar panels so my motivation is to run it MORE when the sun shines, especially like...now...when the water's cold.

Rule of thumb is to "turn over the water each day" but that is actually probably more than you need, maybe even double what you need as long as you're properly chlorinating.

Notice I didn't give you a direct answer....because each pool and situation is different.
