Their website is crazy, BTW. Ah yes, the wild crinoid on the reef definitely is doing so well because of your 200$ piece of calcium. That isn't even a coral. They also have a picture of a mushroom and a vaguely unhappy hammer.

And their "white paper". First of all, the background is black. Misleading. Second, what even is this? They're trying to pass this off as a scientific report, when it's just misleading and self-promotional. I'm sure this was peer-reviewed...
Also is that rampant hair algae?
Why would you use that imagine for marketing a coral plug lol
