Really? How much did you raise Mg by? Did you use a specific brand? I remember an old tank I had with bryopsis and it was only the Kent Tech M that worked so there was speculation that it wasn't the magnesium but something else Kent had in its mixture that did the trick.
How much did you raise mg by? I may use this idea on my coral/clam quarantine. As you said, a little late for the display but that's ok, half the fun is setting things up anyway.
