I’ve seen a lot of conflicting info on this all over the web and even on here. I’m trying to figure out how long to run this thing. I don’t want to run it anymore than I have to obviously. Here’s what I have: I need to run my pump at 2650 rpm (45 Gpm according to intelliflow) in order for the water to smoothly flow over the large spa spillway. That’s the minimum. It’s a wife thing. I have no control over it! It must be flowing all day smoothly! Lol. Anyways at 45 gpm (I assume this is accurate???) that will cycle all my water once through the filter in 4.5 hours. Is that all I need? Do I need to put it through at least twice? Does it have to run a minimum amount of time like 8,9,10 hours instead? Dont want to run it anymore than necessary. Obviously I’m running during day here.
