Throw Dolphin in under the cover before opening?

We’re getting our pool opened for the first time next week. I popped the cover off in a corner to look in there with a light. The water is fairly clear, with some light debris and some green on the floor and walls. Is it worth throwing in the Dolphin in there to clean up a bit before opening? We have a Premier so it has an ultra fine filter I can put in. Or is it not a good idea to disturb it without the pump running?
