I’ve been reading on a lot of studies regarding the fallow period, and I found this interesting one by Humblefish.
First off, I must thank @victoly for bringing this recent study to my attention: https://www.sciencedirect.com/science/article/abs/pii/S0044848617317544 It has now been peer-reviewed and the findings verified by other scientists. I'd also like to share a couple of other related studies (below)...

It says that a tank at 86° can be fallow for just two weeks to rid the tank of ich. I personally won’t risk this, but could I do 86° for the 45 days and have a better success rate then if I did 81° for 45 days? Also in reading, I see that having high flow is incredibly important, as well as blasting all the rock and sand out and using a gravel vac. I will likely do this a few times right at the start of my fallow period. Thoughts?
