That coral will be dead in a month. Ive had a couple pricey tenuis do it from various people. I think it happens because the sellers are dosing certain elements, using supplements you aren't.. If you have success with certain strains of coral from a specific seller/hobbyist-stick with them.
Not what I want to hear, but you may be right. It looked like this in the bag though, so it wasn't caused by chemistry differences. That might affect the recovery though. I guess we will see. Thanks for your input.
