Alkalinity v. Calcium

The fact is that low / high alk or calcium is almost always self induced by the tank owner, and calcium falls at a far slower rate than alkalinity, which often fools noob reefers.

 

Another fact is this article is based on using two part suppliments, and the vast majority of reef tanks I've seen over that past 20 years eventually fail with two parts, or simply drift into stagnation. Contrary to this the majority of reactor driven tanks I've seen over the past 20 years are successful, and don't suffer the problems of this article.

 

At some point I'd like to the authors of these articles to address the issue of different types of calcium availability in reef tanks, including the potential failure of calcium chloride based delivery. I could otherwise take 20 different tanks, set their calcium / alk ratios with spot on parameters, and 7 out of 10 of those tanks won't grow SPS worth a shit.

...or one can use Kalkwasser exclusively (assuming one doesn't have very high rates of alk/cal depletion). Tried-and-true 'old scholl' method that you can use 'indefinitely'.
