Trace elements from calcium reactor

[Dave-T]

There's a "BRSTV Investigates" episode here:

In it, at about 0:50, Randy refers to another episode where they showed that calcium reactor media doesn't contain a meaningful amount of trace elements. I've searched and searched, and I can't find that episode. I'd like to hear more details about what they found. Does anyone have a link for that episode?

Thanks!

The only trace elements that dissolve back into solution are the ones that are bound to the skeleton initially. Most trace elements are utilized by the soft tissue/zooxanthellae rather than the skeleton itself. I would never count on media to provide trace elements and most only provide Ca/Alk with special added media providing mag. Also, coral skeletons will also add a good portion of PO4 as well, some more so than others.

Understood, and thanks. I'd still like to see that video though, I'm curious about the details.

Thanks, but that's not it. He mentions that he was planning to test trace elements in a future video. That's the one I'm looking for.

There was never a video on this specific topic as the ICP test we sent in had almost no trace element content. It would've been a pretty dull and quick episode Like @minus9 said, I wouldn't count on calcium reactor media for trace elements.

Aha! Thanks. So the mystery video, referred to several times, doesn’t actually exist. Tricky. So apparently that means that coral skeletons are made exclusively of calcium.
