Water Parameters through IO?

[ezcompany]

If Instant Ocean is the only salt being used, is there a separate system such as reactors to supplement calcium and alk needs for the stony corals? Or did i miss it in the article.

We do dose Calcium Hydroxide thru a dosing system into the overflow. We also have the main calcium reactor that is on the system which is described in the article. When you get to the section about the reactor you will see three pictures just after the paragraph. The photo in the middle is the calcium reactor.
