How do you guys quickly battle gnats naturally if you’ve came across them? I was thinking about letting my top medium dry out then mist the surface with a water/organic neem oil and then cover the top with sand and diatomaceous Earth

Let your medium get really dry and then cover it with a good layer of sand like you suggested. I wouldn't bother with DE as if it gets wet it won't do anything until its dry again. If you wanna kill em fast you can do what you already had in mind and get mosquito bits/dunks and soak em in your water overnight. They are made with a type of beneficial bacteria that kills fungus gnat larvae. That 2 part plan should knock em out for good in a couple days. I used mosquito bits and already had gnat nix in place(didn't really seem to do anything so don't waste the money) and added some extra airflow over my pots and they were gone in 2 days.

You'r idea is good except for the soil spray with neem oil , generally oil ain't good for any roots and hard ro flush so I would not advise you to do that. You can use the same combo but instead of spraying the soil spray the lower parts of the plant.
