I agree that the pH can take a while to stabilize, as the carbon dioxide level in the mix equilibrates with the ambient air. I'd give a container three hours if there's a small pump running, but I've never measured the time required. The three hours is based on a pH aeration test.

Red Sea advises against mixing for more than 2 hours.
