You can do a few water changes aimed at removing more of the cloudy water if you want. It is like rinsing the substrate in the tank. Keep the vacuum intake as low as you can, and dig in a bit where you can.
If the tank is not yet planted then I would drain it for planting, mist the plants, then refill.
Then turn on the filter. Run it with some floss or quilt batting and check it daily or every other day. Rinse and reuse.
You can start the fishless cycle while working to clear the water.
It really is not a lot of work to get the water clear. Mostly just waiting.
