"And I would never recommend changing anything more then 50% of the water, sorry but 90% of the water is just to much in my opinion."
At that point, there are no fish in the tank anyway, so it will not bother them. What I read was that at the end of the cycle, there will be way too many nitrates for healthy fish, and the water will be quite old. Doing a large water change (the site recommended one 90% or 3 50%) is supposed to get excess nitrates out and reoxygenate the water. Like I said, you probably have much more experience than I do, I just wanted to explain what I wrote.
