Can I leave fluid in the tank until the next time I use it?

Yes, but if it's going to be several weeks before the ultrasonic cleaner will to be used again, you might want to consider pouring the fluid into a plastic bottle. This will help prevent the inside of the tank having a "tide mark" around the inside.
You only need to change the fluid when it gets so dirty you can't see the bottom of the tank.
