Yes, except you don't need to test so often once you get an established tank. Don't go chasing numbers. I only test when my corals tell me to, it's been a few years. Temp and Salinity i check every once in a while.
Yeah, I think that is a good guide, but I would let your tank find its sweet spot and then try to stick with those numbers, don't go chasing after something.
Here is a good video from Red Sea about the different parameters and how they work with your corals.
