True but depending on how tightly closed up your house is this may cause excess CO2 levels lowering PH. my Alk is rock stable but notice PH swings. If I have more people in my house the lower my PH gets. In my case the Soda scrubber solves this and I have personally noticed my corals have been healthier and growth has increased because of it.
Of course everyone's tank conditions are different. What has worked for me might not work for someone else. As in Ryans case he has excellent growth and color despite PH fluctuations.
