It's only a lake shell. Put the tree to your golem totems where you farm ink.

If you have too many nymphs, merge your brothels up, so you have fewer brothels. After you farmed your good items, they will be sleeping.

And if you are further in the game, a level costs up to 6 crowns to enter, so not many levels to play a day. I mostly let in run in the background, occasionally clicking warehouses. And if you pan the camera to one side and put your factories to the other side and only good factories to the side of your viewpoint, less clutter gets auto-harvested.
