Guys I've read an article where it states that due to high levels of CO2 in the Oceans certain species have their calcium "shells" dissolved. "CO2 forms carbonic acid when it dissolves in water, and the oceans are soaking up more and more of it. Recent studies show that the seas have absorbed about a third of all the fossil-fuel carbon released into the atmosphere since the beginning of the industrial revolution, and they will soak up far more over the next century. Yet until quite recently many people dismissed the idea that humanity could alter the acidity of the oceans, which cover 71 per cent of the planet's surface to an average depth of about 4 kilometers. The ocean's natural buffering capacity was assumed to be capable of preventing any changes in acidity even with a massive increase in CO2 levels" Now my question is, is it possible for the CO2 we use for our Ca reactors to cause the same issue in our tanks? I know we try and buffer our tank water but and there's always a but..
