Just curious to see if anyone has first hand experiences with switching from 3/4 inch to 1 inch pump return lines. I'm rebooting my tank and current have 3/4 inch lines from my mag12 to the dt. But the new chiller I bought had 1" outlets and so I was thinking of upsizing.

just wondering if I'll see a large increase in gallons per hour if I redo all my return lines and use 1 inch piping.
