Turn off Pumps at Night?

[mark]

While back was thinking the CL (Dart/3600gph) off in the late evening until early morning, more for noise than anything else, relying on the return (~1000gph) for aeration, etc.

Never did though, partly so not cycling power to Dart (believe easier on pump to stay running and might be a non-issue as never had problems but concerned what if the pump doesn't restart) and return pump only would be giving somewhat laminar flow for period CL off.
