Thanks @MikePaletta, This is all good information and proves there are many ways to keep our systems. I have worked to keep mine simple and consistent. This proves that if you want to make a change to equipment or even livestock do it slowly and one change at a time. Some people I think get bored when they don't have to fiddle with their setup and then make changes just for something to do. I am one that thinks, what can I change to improve things, but then you have to think improve what. My list has been simple, keep on going cost down, keep it stable and make maintenance as easy as possible. It is funny for me as changes happened in my life, I could not just go buy something new anymore because I wanted the newest available piece of equipment. Now every time I think about it, I only do so because there was a valid reason. Everything has now become more stable and as the tank becomes more mature coral growth and color keeps improving. I don't do real water change where I change out a particular amount of water on a periodic basis but since I normally skim on the wet side I do have to maintain salinity so I go through enough salt that would be equivalent to 10 percent every 30-60 days. The two articles just seem to help remind us what is really important stability.
