You Should not need to dry the substrate. This will kill a very large portion of your biofilter and you will have to cycle the tank again. It is relatively easy to remidy ich by interuptiong one of the three life stages. By raising the water temp and adding aquarium salts, you can kill the paracite while it is in its "free swimming" stage. While ich is in its egg stage, it is unaffected by medications so by thoroughly vaccuming the gravel every day for a little while, you will remove the eggs that have harbored in your gravel while also improving your water quality(better for the fish). If you have a planted tank, vaccuming will be very invasive to your substrate and potentially damage plant roots. I ran into ich shortly after i began keeping fish. The medications seemed to put a great deal of stress on the fish. After a great deal of internet research the previous method is what I landed on. It took about two or three weeks for me to feel comfortable that the ich was resolved but i have never had a problem since and I still have all the fish.
